APPLICATIONS
Telecom / Datacom Wireless Networks Optical Network Equipment Server and Data Storage Industrial / Testing Equipment OPTIONS 3.3V or 5V management Power Delphi Series DIM, 300W Dual Input Power Processing DC/DC Power Modules The Delphi DIM series, 300W dual re dundant input power processing isolated DC/DC converter is the latest offering from a world leader in power system and technology and manufacturing ― Delta Electronics, Inc. This product family provides up to 300 watts of power in an industry standard footprint and pinout. The DIM series is designed to simplify the task and reduce the board space of implementing dual redundant, hot swappable 48Vdc power distribution with EMI filtering and inrush current limiting for an ATCA ( Advanced Telecommunications Computing Architecture) or other telecom boards. In addition to processing the dual redundant 48V bus, the DIM module also provides isolated auxiliary 3.3V or 5V (8 W), and/or 5V (100mA) BLUE_LED power for other housekeeping functions. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performances, as well as extremely high reliability under highly stressful operating conditions. All models are fully protected from abnormal input/output voltage, current, and temperature conditions. The Delphi DIM series converters meet all safety requirements with basic insulation.

DS_DIM3R3_03252009 FEATURES AND DESIGN CONSIDERATIONS (CONTINUED) The PICMG 3.0’s requirements for the 0 Vdc transient is 5mS with 50V/ms fall slew rate and 12.5 V/ms rise slew rate. This requirement will lead to a 9.3ms T_HLDP requirement assuming power is interrupted at -43Vdc (Vth). Considering power output is 300W, Vth is 43V, )(16724372 3.9*300*2_ 22 uFHLDPC =−= When the input voltage is at the threshold of discharge, C_HLDP will go off line and the charge pump will recharge it to 72V. The discharge resistor for C_HLDP is not required, because there is sufficient standby current in the module to bleed the holdup capacitors from 75V to 60V within 1 second as specified in the PICMG 3.0. Furthermore a bleed resistor will induce extra loss of the MOSFET of the charging circuit. Over-Current Protection DIM3R3/050 provides two over current protection levels. When the output current ex ceeds the low current limit level, the current will be kept for a period of time before the module is shut down. After a fixed delay time, the module will try to restart. If the output current exceeds the high current limit level, the module will shut down immediately. Then it will go through the same restarting procedure. A/B Feed / Fuse Alarm (-48V_ALARM) The input feeds A and B are monitored. The module will send an opto-isolated signal if any of the feed is below the voltage threshold (typical 35V). Therefore, the loss of any A or B feed can be detected. The opto coupler transistor on state indicates a normal status and off state indicates a fault condition. Input Under Voltage Lockout The input under-voltage lockout prevents the module from being damaged by low input voltage. When the input voltage is lower than its threshold voltage, the module will be turned off. The lockout occurs between -33.3V to -35.3V. Transient Over Voltage Protection The PICMG 3.0 requires the module work normally under 200V/5μS and 100V/10μS input voltage transient. DIM3R3/050 can meet the requirement. An internal TVS with 80V/1500W peak pulse power rating will suppress the 200V transient voltage. For the 100V pulse voltage, the power train impedance will damp it below internal components rating without shut down the module. When input voltage of the module is higher than 81.8V, the module will be turned off. The module will restart when the input voltage drop down to 79.8V. Management Power and Blue_LED Power The module contains two isolated DC output. The first output provides up to 8W of 3.3V (DIM3R3) or 5.0V (DIM050) management power (reference to LOGIC_GND). This power is used to power the IPM controller for the ATCA board or to power up system controller for other applications. The second isolated output, 5V/100mA, is used to power the Blue LED per PICMG 3.0 requirement. The management power is available as soon as the input voltage levels are within –36Vdc to –75Vdc. The output is short circuit and over voltage protected. The module is in a hiccup mode under an OCP or short output condition. The output voltage will keep constant under over voltage status. No additional output capacitors are required, but a 22µF tantalum/ceramic and a 0.01µF to 0.1µF ceramic capacitors are highly recommended to reduce the switching ripple and noise. Higher output capacitance may be required in case of large input line or output load transient conditions.
