PRODUCT OVERVIEW
Murata Power Solutions' MAPC-104 non-isolated, triple output DC/DC converter is designed to power the Cisco 3200 Mobile Access Router and is compliant to PC/104-Plus specifications. The equipment ideally suites integration into public safety, defense, homeland security and commercial transportation vehicles, whether on land, in water or air, and is employed for powering secure data, voice and video communications across multiple wireless networks. The MAPC-104 is a high performance, compact and rugged power supply which operates in the harshest conditions, withstanding input transient voltages according to SAE J1455 and J1211. It converts the vehicle's standard battery voltage of 12V or 24V (VIN range from 9 to 32 Volts) to three fully regulated outputs of 3.3V @ 6A, 5.1V @ 6.3A and 12V @ 100mA up to a total output power of 46 Watts. Taking full advantage of a synchronousrectifier, buck/boost topology, MAPC-104's boast outstanding efficiency of up to 92.5%, enabling full-power operation to ambient temperatures as high as +85C with 100 lfm air flow. The compact 3.775" x 3.55" x 0.60" (95.9 x 90.2 x 15.2mm) open frame, triple output DC/DC power card is mechanically and electrically compliant to PC/104-plus specifications. Operating with the Cisco designed system cards, the MAPC-104 is considered part of the host, which requires the 3.3V (but no -5V/-12V) supply provided. Assembled using fully automated, SMT-on-pcb techniques, MAPC-104s provide stable no-load operation, excellent line and load regulation (1% max.), quick step response (200sec), and low output ripple/noise (25mVp-p). All devices feature full I/O fault protection including: input overvoltage and undervoltage shutdown, power up/down sequencing, output overvoltage, output current limiting, short-circuit protection, power good (LED indicator and external signal), overtemperature warning and thermal shutdown. All models are certified to IEC/EN/UL60950-1 safety standards. Selected models include RoHS compliance.

The contacts are rated at 5 Amps 250Vac. However, whatever current is drawn must be summed with current powering the PC-104 system. A suggested mating connector is AMP/Tyco Electronics MTA-100 Series, part number 647000-2. See also the CST-100 Series.
For the MAPC-104-5V model version, spare +5 Vdc power may be taken from the P2 connector which is adjacent to the pin 1 end of the J1 connector (see drawings). Be aware that this power is generated on the MAPC-104 and therefore is in addition to whatever 5V current is used by the host PC-104 system. All power characteristics (regulation, tempco, ripple, etc.) are derived from the MAPC-104.

Performance/Functional Specifications
Typical @ TA = +25C under nominal line voltage and full-load conditions unless noted. Input
Non-Isolated, DC/DC Converters 3.3, 5.1 & 12.4, 46W Mobile Applications
All models are tested and specified with a single, external, 0.1F, multi-layer ceramic output capacitor on each output and no external input capacitors, unless otherwise noted. All models will effectively regulate under no-load conditions (with perhaps a slight increase in output ripple/noise). See Technical Notes/Performance Curves for additional explanations and details. Input Ripple Current is tested/specified over a 5-20MHz bandwidth with an external 33F input capacitor and a simulated source impedance of 220F and 12H. See I/O Filtering, Input Ripple Current and Output Noise for details. The Current-Limit-Inception point is the output current level at which the converter's power-limiting circuitry drops the output voltage 3% from its initial value. See Output Current Limiting and Short-Circuit Protection for more details. See Dynamic Load Response for detailed results including switching frequencies. For Start-Up-Time specifications, output settling time is defined as the output voltage having reached 1% of its final value and the load current having reached at least 80% of its final value. MTBF is calculated using TELCORDIA SR-332 Method 1 Case 3, Issue 1, ground fixed, +30C ambient air and full-load conditions. All models are fully operational and meet all published specifications, including "cold start," at -40C. The highly unlikely, simultaneous failure of several specific on-board components could result in the MAPC-104's input voltage appearing at its output, despite the unit's output overvoltage protection mechanisms. In this rare situation, the Power Good signal (IPH pin 2, Pwr_LED_Drive) will be deactivated and systems monitoring Power Good will eventually shut down. If you are using an MAPC-104 to power a load that must be protected against any and all possible overvoltages, no matter how rare, you will have to provide the protection external to the MAPC-104. Please contact MPS for recommendations.

Physical
Connector Designations The official PC/104 bus specification identifies the standard interboard bus connections as paired J1/P1 and J2/P2 on one side and J3/P3 on the other side. However, J1/P1/J2/P2 is physically all one big 4-row connector with J1/J2 bus receptacle sockets (female) on the top side and P1/P2 pins (male) on the bottom. This arrangement provides interboard pass-through connections between PC/104 boards. MPS refers to this single connector as "J1." MPS's auxiliary connectors (the IPH and the 5V Auxilliary Power Connector) are internally designated P1 and P2 respectively and this nomenclature may appear on the board silkscreening. This is purely an artifact of automated sequential part numbering in our CAD system and has no relation to the standard PC/104 interboard bus connectors. Don't get the connectors confused since they are all very different types and locations!

Self-Protection Features The MAPC-104 contains two systems for protection of out-of-limit voltages, currents and temperature. These systems control two output lines located on the Input Power Header connector. Both systems operate independently and concurrently. The MAPC-104 will respond to both temperature and voltage/ current simultaneously. The output circuits for both these controls are shown below. Both of them will drive either an external LED lamp and/or a logic circuit. The Overtemperature Warning Circuit assumes that an external pullup resistor is supplied by the user. The Power Good Circuit ("Pwr_LED_Drive Out") includes an on-board pullup resistor to drive an external LED with about 15mA. Pwr_LED_Drive Out (pin 2, pullup to internal +5V): HI (transistor off) = Power is normal. LED lamp is illuminated. LO (transistor on) = Power fault, LED lamp is dark Overtemperature Operation The overtemperature system includes a on-board temperature sensor, a local microcontroller with A/D inputs, a timer and hysteresis so that the user may take steps to prevent inadvertant shut down. Operation proceeds as follows: If the on-board temperature exceeds +115C, the OT_Warn Output is asserted (LO) by the microcontroller and an internal 30 second software timer is started. The outputs remain powered on. If the 30-second timer has not expired and the on-board temperature cools below +110C, the OT_Warn Output will be deasserted (HI) and operation will continue unchanged. If the 30-second timer has expired and the temperature still exceeds +115C, the outputs will shut down. As soon as the on-board temperature cools to less than +110C, the MAPC-104 will automatically restart and power will be restored to the outputs. The 5 degree hysteresis between 110 and 115C prevents rapid cycling of the OT_Warn Output. If the on-board temperature reaches +125C, the outputs will shut down, regardless of the state of the 30-second timer. The temperature must cool to less than +110C for auto restart.

The transistors in these outputs are either on (typically less than 0.4 Volts out) or off (high impedance state). Depending on how the user wires the external circuit, these indicators have the following sense:

Non-Isolated, DC/DC Converters 3.3, 5.1 & 12.4, 46W Mobile Applications
Power Good Operation Local power is measured by several circuits shared with the overtemperature system. The Pwr_LED_Drive Output is indirectly controlled by the on-board microcontroller. The on-board PWM switching controller measures +3.3V and +5V output voltages and all output currents. The microcontroller measures input voltage and the +12V output voltage. The system requires that the input voltage is within normal tolerances at all times. If the input voltage is too high very briefly at startup (but not exceeding the absolute input voltage), the system will start normally if the input voltage reaches acceptable limits quickly (under half a second). This typically occurs as a load is applied. When the system first starts, the Power Good LED (if installed) remains dark briefly until all on-board startup conditions are met (less than half a second) at which point the LED is illuminated. The operation proceeds as follows: If the outputs on any lines deviate from approximately 7% of nominal and/or the output current is excessive, the outputs are all shut down and the Pwr_LED_Drive Output is desasserted (LO, lamp dark). The system will attempt to restart in about half a second by briefly turning on all outputs. If successful and the fault is eliminated, the Pwr_LED_Drive Output will be asserted (HI, lamp lit) and operation continues. If the fault condition remains, the system will attempt to restart two more times, spaced about half a second apart. If the fault remains for the third time, the system will shut down and will not retest the fault. The system must now be restored by fully cycling the input power. The 3-fault countdown only occurs if the fault does not recover continuously throughout the attempted restart interval. An occasional random shutdown and successful restart will not trigger the 3-fault counter. However, external logic should record the frequency and quantity of such shutdowns. RoHS-5 compliance refers to the exclusion of the six hazardous substances in the RoHS specification with the exception of lead. MPS's RoHS-5 products use all the conforming RoHS materials, however our solders are Sn63/Pb37.
