INNOVATION and EXCELLENCE
Single Output
A-Series, UWR Models
High-Density, 1" x 2" 6 Amp/15 Watt, 1.2-15VOUT DC/DC's
The new 1.2, 1.5V, 1.8V and 2.5V models in DATEL's flagship 7-15 Watt A-Series can source a continuous 6 Amps. This is the most "low-voltage" current available from a standard 1" x 2" package, and these power converters exemplify DATEL's relentless drive to bring you more power/current, from standard packages, without compromising reliability or resorting to thermal specmanship. By combining a high-frequency, high-efficiency (to 88%), synchronous-rectifier topology with the newest components and time-tested, fully automated, SMT-on-pcb construction, these UWR Models are able to bring you 7-15W (@ up to 6A) in the standard 1" x 2" package from which most competitors can only get 5-10W (@ 3-4A). All UWR's deliver their full output power over ambient temperature ranges from -40C to as high as +70C (model and input voltage dependent) without heat sinks or supplemental forced-air cooling. Devices derate to +100C. Output voltages are 1,2, 1.5, 1.8, 2, 2.5, 3.3, 5, 12 or 15 Volts. Input voltage ranges are 10-18V (D12 models), 18-36V (D24 models) or 36-75V (D48 models). All models feature input pi filters, input undervoltage and overvoltage lockout, input reverse-polarity protection, output overvoltage protection, output current limiting, and continuous short-circuit protection. On/off control and output-trim functions are optional (see Optional Functions). All models are certified to IEC950, UL1950 and EN60950 safety requirements. D48 models (36-75V inputs) are CE marked. UWR 7-15W DC/DC's are packaged in low-cost, light-weight, diallyl phthalate (UL94V-0 rated) plastic packages with standoffs. EMC compliance is achieved via a low-noise design rather than through expensive metal shielding.

All models are specified with two external 0.47F multi-layer ceramic capacitors installed across their output pins. See Minimum Output Loading Requirements under Technical Notes. See Technical Notes for details. The On/Off Control and Trim functions are optional and must be installed by DATEL. See Optional Functions or contact DATEL for details. The On/Off Control is designed to be driven with open-collector logic or the application of appropriate voltages (referenced to -Input, pin 2). Applying a voltage to the On/Off Control pin when no input voltage is applied to the converter may cause permanent damage. See Technical Notes. Output noise maybe further reduced with the addition of additional external output capacitors. See Technical Notes. Operating temperature range without derating is model and input-voltage dependent. See Temperature Derating.

NOTES
Trimming Output Voltages These converters have a trim capability (pin 5) that allows users to adjust the output voltage 5%. Adjustments to the output voltage can be accomplished via a trim pot, Figure 2, or a single fixed resistor as shown in Figures 3 and 4. A single fixed resistor can increase or decrease the output voltage depending on its connection. Fixed resistors should have an absolute TCR less than 100ppm/C to minimize sensitivity to changes in temperature. A single resistor connected from the Trim (pin 5) to the +Output (pin 4), see Figure 3, will decrease the output voltage. A resistor connected from the Trim (pin 5) to Output Common (pin 6) will increase the output voltage. Trim adjustment greater than 5% can have an adverse effect on the converter's performance and is not recommended.
4 +OUTPUT +INPUT
Floating Outputs Since these are isolated DC/DC converters, their outputs are "floating." Designers will usually use the output Common (pin 6) as the ground/return of the load circuit. You can, however, use the +Output (pin 4) as ground/return to effectively reverse the output polarity. Minimum Output Loading Requirements 1.2 to 5V models employ a synchronous-rectifier design topology. All models regulate within spec and are stable under no-load conditions. 12/15V models employ a traditional forward architecture and require 10% loading (125mA for 12V models, 100mA for 15V models) to achieve their listed regulation specs. 12/15V models also have a minimum-load-for-stability requirement (25mA). For 12/15V models, operation between 25mA and 10% loading will result in stable operation but regulation may degrade. Operation under no-load conditions will not damage the 12/15V devices; however they may not meet all listed specifications. Filtering and Noise Reduction

All A-Series UWR DC/DC Converters achieve their rated ripple and noise specifications using the external input and output capacitors specified in the Performance/Functional Specifications table. In critical applications, input/ output noise may be further reduced by installing additional external I/O caps. Input capacitors should be selected for bulk capacitance, low ESR and high rms-ripple-current ratings. Output capacitors should be selected for low ESR and appropriate frequency response. All caps should have appropriate voltage ratings and be mounted 2-3 inches from the converter to achieve published ratings. The most effective combination of external I/O capacitors will be a function of your particular load and layout conditions. Our Applications Engineers will be happy to recommend potential solutions and can discuss the possibility of our modifying a given device's internal filtering to meet your specific requirements. Contact our Applications Engineering Group for additional details. Input Fusing Certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. Fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists. For DATEL A-Series UWR 7-15 Watt DC/DC Converters, you should use slow-blow type fuses with values no greater than the following.

Start-Up Threshold and Undervoltage Shutdown Under normal start-up conditions, devices will not begin to regulate until the ramping-up input voltage exceeds the Start-Up Threshold Voltage (35V for "D48A" models). Once operating, devices will not turn off until the input voltage drops below the Undervoltage Shutdown/Lockout limit (34V for "D48A" models). Subsequent re-start will not occur until the input is brought back up to the Start-Up Threshold. This built-in hysteresis obviously avoids any indeterminate on/off situations at a single voltage.

The VIN to VOUT Start-Up Time is the interval between the time at which a ramping input voltage crosses the turn-on threshold point and the fullyloaded output voltage enters and remains within its specified accuracy band. Actual measured times will vary with input source impedance, external input capacitance, and the slew rate and final value of the input voltage as it appears to the converter. The On/Off to VOUT Start-Up Time assumes the converter is turned off via the On/Off Control with the nominal input voltage already applied to the converter. The specification defines the interval between the time at which the converter is turned on and the fully-loaded output voltage enters and remains within its specified accuracy band.

Output Power (Watts)
The thermal performance of A-Series UWR 7-15 Watt DC/DC Converters is depicted in the derating curves shown below. All devices, when operated at full load, in still ambient air, over their full specified input voltage range, can safely operate to TA maximum. All models, other than the D12A models (10-18 Volt input range), can operate at higher ambient temperatures if the input range is narrowed. For example, model UWR-5/3000-D48A can operate safely to +70C if the input range is kept between 36 and 48 Volts. Contact DATEL's Applications Engineering Group if you need additional details.

PART
NUMBER
STRUCTURE
Adaptations There are various additional configurations available on A-Series 7-15W DC/DC's. Because designating each of them with a standard part-number suffix would result in an unmanageable matrix of part numbers, such are designated by DATEL and assigned 5-digit "part-number suffixes. Once a configuration has been requested by a customer and created by DATEL, the resulting product is available to any customer as a "standard" off-the-shelf product. Consequently, the following products are offered for sale: UWR-3.3/4250-D48AT-30690 Standard product, 48VIN, 3.3VOUT/4.25A with a VOUT Trim function added in the pin 3 position, with adapted current limit set point to 6.5A min. and with removed Input Overvoltage Shutdown function. UWR-5/3000-D48ACT-30770 Standard product, 48VIN, 5VOUT/3A with On/Off Control function (positive polarity) on pin 3, VOUT Trim function added on pin 5. Adaptations: Trim equations are Tyco/Lucent-compatible. Transformer isolation system has been enhanced to meet the BASIC INSULATION requirements of UL60950/EN60950. I/O pins are 25-mil-square Tyco/Lucent compatible. Shielded metal case is connected to +VIN pin 1. Input Overvoltage Shutdown function has been removed.

Output Configuration: U = Unipolar Wide Range Input Nominal Output Voltage: 1.2, 1.5, 1.8, 2, 2.5, 3.3, 5, 12 or 15 Volts Maximum Output Current in mA Optional Functions A-Series High Reliability Input Voltage Range: D12 = 10-18 Volts (12V nominal) D24 = 18-36 Volts (24V nominal) D48 = 36-75 Volts (48V nominal)
Options and Adaptations
Optional Functions The versatile A-Series 7-15W DC/DC Converters offer numerous electrical and mechanical options. Per the Ordering Guide on page 2, the trailing "A" (for A-Series) in each part number pertains to the base part number. Partnumber suffixes are added after the "A," indicating the selection of standard options. The resulting part number is a "standard product" and is available to any customer desiring that particular combination of options. As described below, selecting certain options will result in the installation of additional pins in certain locations. Suffix Description Blank No VOUT Trim or On/Off Control functions added (no I/O pins installed in the pin 3 and pin 5 positions). The pin length remains at 0.2 inches (5.08 mm). T C CT N NT L1 L2 Add a VOUT Trim function on pin 5. No pin 3 installed. Add an On/Off Control function on pin 3 (with positive polarity). No pin 5 installed. Add the On/Off Control function (with positive polarity) on pin 3 and add the VOUT trim function on pin 5. Add an On/Off Control function on pin 3 with negative polarity. No pin 5 installed. Add the On/Off Control function with negative polarity on pin 3 and add the VOUT trim function on pin 5. Trim the pin length to 0.110 0.010 inches (2.79 0.25mm). This option requires a 100-piece minimum order quantity. Trim the pin length to 0.145 0.010 inches (3.68 0.25mm). This option requires a 100-piece minimum order quantity.
Contact DATEL directly if you are interested in your own set of options/ adaptations. Further examples of such include, but are not limited to the following: Competitor-compatible pin shape and/or length, instead of DATEL's standard 40-mil round pins. Shielded metal case connected to the I/O pin of your choice. Electrical modification of the VOUT-Trim functionality/equations and/or the On/Off Control function to be competitor-compatible. Raising the Input Overvoltage Lockout/Shutdown trip point to a level that enables the device to experience brief input transients (of known peak value and duration) without shutting down. For example, we can move the threshold to +110V for applications that anticipate 100V, 100msec input transients.
