An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a time-delay fuse with a maximum rating of 5 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer's data sheet for further information.

These converters have been evaluated to the spacing requirements for Basic Insulation, per the above safety standards. For Basic Insulation models ("-B" Suffix), 1500 Vdc is applied from VI to VO to 100% of outgoing production. For end products connected to -48 Vdc, or -60 Vdc nomianl DC MAINS (i.e. central office dc battery plant), no further fault testing is required. Note:-60 V dc nominal bettery plants are not available in the U.S. or Canada. For all input voltages, other than DC MAINS, where the input voltage is less than 60 Vdc, if the input meets all of the requirements for SELV, then: SCOPE RESISTIVE LOAD n LTEST 12 H CS 220 F ESR < 0.1 @ 20 C, 100 kHz CURRENT PROBE VI(+) BATTERY 33 F ESR < 0.7 @ 100 kHz VI(-) Note: Measure input reflected ripple current with a simulated source inductance (LTEST) of 12H. Capacitor CS offsets possible battery impedance. Measure current as shown above. Figure 37. Input Reflected Ripple Current Test Setup. COPPER STRIP VO(+) 1.0 F VO(-) 10 F The output may be considered SELV. Output voltages will remain withing SELV limits even with internally-generated non-SELV voltages. Single component failure and fault tests were performed in the power converters. One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. GROUND PLANE n Note: Scope measurements should be made using a BNC socket, with a 10 F tantalum capacitor and a 1 F ceramic capcitor. Position the load between 51 mm and 76 mm (2 in and 3 in) from the module Figure 38. Peak-to-Peak Output Ripple Measurement Test Setup. For all input sources, other than DC MAINS, where the input voltage is between 60 and 75 Vdc (Classified as TNV-2 in Europe), the following must be adhered to, if the converter's output is to be evaluated for SELV: n CONTACT AND DISTRIBUTION LOSSES n The input source is to be provided with reinforced insulation from any hazardous voltage, including the AC mains. One VI pin and one VO pin are to be reliably earthed, or both the input and output pins are to be kept floating. Another SELV reliability test is conducted on the whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module's output. VI(+) II SUPPLY VI(-) CONTACT RESISTANCE VO(+) IO LOAD n VO(-) Note: All voltage measurements to be taken at the module terminals, as shown above. If sockets are used then Kelvin connections are required at the module terminals to avoid measurement errors due to socket contact resistance. The power module has ELV (extra-low voltage) outputs when all inputs are ELV. All flammable materials used in the manufacturing of these modules are rated 94V-0, and UL60950A.2 for reduced thicknesses. The input to these units is to be provided with a maximum 5A time-delay in the unearthed lead. Figure 39. Output Voltage and Efficiency Test Setup.

This is accomplished by connecting an external resistor between the TRIM pin and either the VO(+) or VO(-) pins. The trim resistor should be positioned close to the module. If not using the trim feature, leave the TRIM pin open. With an external resistor Trim-down between the TRIM and VO(-) pins, the output voltage set point VO, set decreases (see Figure 41). The following equation determines the required external-resistor value to trim-down the output voltage from VO, set to VO: The power module should be connected to a low ac-impedance source. A highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 37, a 33F electrolytic capacitor (ESR<0.7W at 100kHz), mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines. Feature Descriptions Remote On/Off Two remote On/Off options are available. Positive logic remote On/Off turns the module on during a logic-high voltage on the remote ON/OFF pin, and off during a logic low. Negative logic remote On/Off, device code suffix "1", turns the module off during logic-high voltage and on during a logic low. To turn the power module on and off, the user must supply a switch to control the voltage between the ON/OFF pin and the VI(-) terminal. The switch may be an open collector or equivalent (see Figure 40). A logic low is Von/off = -0.7 V to 1.2 V. The maximum Ion/off during a logic low is 1 mA. The switch should maintain a logic-low voltage while sinking 1 mA. During a logic high, the maximum Von/off generated by the power module is 15 V. The maximum allowable leakage current of the switch at Von/off = 15 V is 50 A. If not using the remote on/off feature, do one of the following: For positive logic, leave the ON/OFF pin open. For negative logic, short the ON/OFF pin to VI(-).

Circuit Configuration to Increase Output Voltage. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (maximum rated power = VO, set x IO, max). Figure 41. Circuit Configuration to Decrease Output Voltage. With an external resistor Rtrim-up, connected between the TRIM and VO(+) pins, the output voltage set point VO, set increases (see Fiugre 42). The following equation determines the required external-resistor value to trim-up the output voltage from VO, set to VO: Overcurrent Protection To provide protection in an output overload fault condition, the module is equipped with internal current-limiting circuitry, and can endure current limiting for an unlimited duration. At the instance of current-limit inception, the module enters a "hiccup" mode of operation, whereby it shuts down and automatically attempts to restart. While the fault condition exists, the module will remain in this mode until the fault is cleared. The unit operates normally once the output current is reduced back into its specified range.

This control loop has a higher voltage set point than the primary loop (See the overvoltage clamp values in the Feature Specifications Table). In a fault condition, the overvoltage clamp ensures that the output voltage does not exceed VO, ovsd, max. This provides a redundant voltage-control that reduces the risk of output overvoltage. For example, to trim-up the output voltage of 1.5 V module (HW012A0M) by 8% to 1.62 V, Rtrim-up is calcualted is as follows: D% = 8 A = 19.8 B = 1089 C = 104 19.8 ( 100 + 8 ) - 1089 R trim-up = --------------------------------------------------- - 104 k 8 R trim-up = 27.175k Lineage Power 14 Data Sheet June 26, 2009 Feature Descriptions (continued) Overtemperature Protection HW006/010/012 Series Power Modules; dc-dc Converters 36-75 Vdc Input; 1.2 Vdc to 5 Vdc Output; 6.6A to 12A To provide protection under certain fault conditios, the unit is equipped with a thermal shutdown circuit. The unit will shudown if the overtemperature threshold is exceeded, but the thermal shut down is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restart after it cools down. Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold.

Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring drain pin Q203 at the position indicated in Figure 43. The temperature at Q203 drain pins should not exceed 115 C. The output power of the module should not exceed the rated power for the module (VO, set x IO, max). Although the maximum operating ambient temperature of the power modules is 85 C, you can limit this temperature to a lower value for extremely high reliability. 8 6 4 2 0 2.0 m/s (400 ft./min.) 1.0 m/s (200 ft./min.) 0.5 m/s (100 ft./min.)

Heat Transfer via Convection Increasing airflow over the module enhances the heat transfer via convection. Figures 44--48 show the maximum current that can be delivered by various modules versus local ambient temperature (TA) for natural convection through 2 m/ s (400 ft./min.). Systems in which these power modules may be used typically generate natural convection airflow rates of 0.3 ms-1 (60 ft./min.) due to other heat-dissipating components in the system. Therefore, the natural convection condition represents airflow rates of up to 0.3 ms-1 (60 ft./min.). Use of Figure 44 is shown in the following example.

The minimum recommended nozzle diameter for reliable operation is 6mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 9 mm. Oblong or oval nozzles up to 11 x 9 mm may also be used within the space available. For further information please contact your local Lineage Power Technical Sales Representative. Through-Hole Lead-Free Soldering Information The RoHS-compliant through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process. If additional information is needed, please consult with your Lineage Power representative for more details. Reflow Soldering Information The HW006 family of power modules is available for either Through-Hole (TH) or Surface Mount (SMT) soldering. These power modules are large mass, low thermal resistance devices and typically heat up slower than other SMT components. It is recommended that the customer review data sheets in order to customize the solder reflow profile for each application board assembly. The following instructions must be observed when SMT soldering these units. Failure to observe these instructions may result in the failure of or cause damage to the modules, and can adversely affect long-term reliability. The surface mountable modules in the HW006 family use our newest SMT technology called "Column Pin" (CP) connectors. Figure 50 shows the new CP connector before and after reflow soldering onto the end-board assembly. Surface Mount Information Pick and Place Area Although the module weight is minimized by using openframe construction, the modules have a relatively large mass compared to conventional surface-mount components. To optimize the pick-and-place process, automated vacuum equipment variables such as nozzle size, tip style, vacuum pressure, and placement speed should be considered. Surface-mount versions of this family have a flat surface which serves as a pick-and-place location for automated vacuum equipment. The module's pick-and-place location is identified in Figure 49. HW006 Board Insulator Solder Ball X 14mm (0.57in) End assembly PCB 21mm (0.84in) Figure 49. Pick and Place Location. Z Plane Height The 'Z' plane height of the pick and place location is 7.50mm nominal with an RSS tolerance of +/-0.25 mm. Nozzle Recommendations The module weight has been kept to a minimum by using open frame construction. Even so, they have a relatively large mass when compared with conventional SMT components. Variables such as nozzle size, tip style, vacuum presLineage Power Figure 50. Column Pin Connector Before and After Reflow Soldering. The CP is constructed from a solid copper pin with an integral solder ball attached, which is composed of tin/lead (Sn/Pb) solder. The CP connector design is able to compensate for large amounts of co-planarity and still ensure a reliable SMT solder joint. Typically, the eutectic solder melts at 183oC, wets the land, and subsequently wicks the device connection. Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. There are several types of SMT reflow technologies currently used in the industry. These surface mount power modules can be reliably soldered using natural forced convection, IR (radiant infrared), or a combination of convection/IR. For reliable soldering the solder reflow profile should be established by accurately measuring the modules CP connector temperatures. 18 Data Sheet June 26, 2009 HW006/010/012 Series Power Modules; dc-dc Converters 36-75 Vdc Input; 1.2 Vdc to 5 Vdc Output; 6.6A to 12A ages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of < 30C and 60% relative humidity varies according to the MSL rating (see J-STD-033A).

Solder Ball and Cleanliness Requirements The open frame (no case or potting) power module will meet the solder ball requirements per J-STD-001B. These requirements state that solder balls must neither be loose nor violate the power module minimum electrical spacing. The cleanliness designator of the open frame power module is C00 (per J specification). Lead Free Soldering The -Z version SMT modules of the HW/HC series are leadfree (Pb-free) and RoHS compliant and are compatible in a Pb-free soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. Pb-free Reflow Profile Power Systems will comply with J-STD-020 Rev. C (Moisture/ Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package (table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Figure. 53. MSL Rating The HW series SMT modules have a MSL rating of 1.
