preliminary datasheet ds_dim3r3_08292008 9 features and design considerations introduction the dim3r3/050 module is designed to simplify the task and reduce the board space of an atca (advanced telecommunications computing architecture) power entry distribution requirements in the system board. the main functionality of the module is to provide dual, redundant -48v a/b feed or?ing, inrush protection for hot swap capability, emi filtering to attenuate the noise generated by the downstream dc/dc converters, and a 72v output voltage for charging the holdup capacitor. the module also has a management power supply which provides an 8w, 3.3v or 5v management power and/or a 5v/100ma output (optional) to power the blue led per picmg 3.0 requirement. the module provides a/b feed/fuse open alarm, over current protection, over voltage protection, and over temperature protection. it also provides input under voltage lock-out and input reverse polarity protection. a/b feed or?ing to improve the total power di stribution efficiency, four internal mosfets are used to function as the or?ing diodes. a control circuit is designed to keep about 100mv voltage drop across mosfet. during full load operation, the mosfets are fully turned on. during light load, the mosfets work under a high rdson condition. if the output current decreases to zero, the mosfets will be turned off. this design provides module a reverse voltage sustain function. the module shall not be damaged from reverse polarity connection in the event of mis-wiring of either in put feeds at the shelf input terminals. furthermore, a fast shut down circuit is designed for the negative current case. this design protects the common dc bus against hard short faults at the sourcing power supply output. hot swap functionality the hot-swap function is designed to limit the inrush current charged to the bulk capacitor of the down stream bus converter. the current value and duration comply with the picmg 3.0?s inrush transient specs. although the inrush current for bulk capacitor is under control, special attentions need to be paid to the current for emi filter because this ci rcuit is in front of hot-swap circuit. emi filtering an internal emi filter is designed for the atca board to meet the system conducted emission requirements of cispr 22 class b when used with delta dc/dc converters. figure 17 shows the emi performance of dim3r3 when it worked with delta power module q48sh12025nrfa (36~75vin, 12v/25a output quarter brick). it meets cispr 22 class b requirement. figure 11: emi test result with q48sh12025nrfa: holdup capacitor charging current (72v_cap) an off line holdup capacitor (c_hldp) is needed to store energy for the holdup time requirement. c_hldp is charged to 72v (+/- 3% to lerance). for a fixed energy storage requirement, high capacitor voltage reduces capacitor capacitance and size. a constant current circuit charges c_hldp before its voltage reaches the high limitation and isolates it from power train circuit. the discharge switch will tu rn on if both a&b feeds have dropped below ?38v (typical). c_hldp will be connected to power train and provided the energy for system operation. c_hldp is calculated by the following equation: 2 2 72 _ * * 2 _ vth v hldp t power hldp c ? = where power is the input power to the downstream dc/dc converter; t_hldp is the holdup time requirement; vth is the minimum input voltage threshold of the downstream dc/dc converter.
preliminary datasheet ds_dim3r3_08292008 10 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, ) ( 1672 43 72 3 . 9 * 300 * 2 _ 2 2 uf hldp c = ? = 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/5 s and 100v/10 s 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 22f tantalum/ceramic and a 0.01f to 0.1f 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.
preliminary datasheet ds_dim3r3_08292008 11 thermal considerations thermal management is an important part of the system design. to ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the modul e. convection cooling is usually the dominant mode of heat transfer. hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. thermal testing setup delta?s dc/dc power modules are characterized in heated vertical wind tunnels t hat simulate the thermal environments encountered in most electronics equipment. this type of equipment commonly uses vertically mounted circuit card s in cabinet racks in which the power modules are mounted. the following figure shows the wind tunnel characterization setup. the power module is mounted on a test pwb and is vertically positioned within the wind tunnel. the space between the neighboring pwb and the top of the power modul e is constantly kept at 6.35mm (0.25??). note: wind tunnel test setup figure dimensions are in millimeters and (inches) 12.7 (0.5?) module a ir flo w 50.8 ( 2.0? ) facing pwb pwb air velocit y and ambient temperature measured below the module figure 12: wind tunnel test setup thermal derating heat can be removed by increasing airflow over the module. to enhance system reliability, the power module should always be operated below the maximum operating temperature. if the temperature exceeds the maximum module temperature, reliability of the unit may be affected. thermal curves figure 13: temperature measurement location * the allowed maximum hot spot temperature is defined at 117c dim3r3300(standard) output current vs. ambient temperature and air velocity @vin = 48v; 3.3v&5v=8w (transverse orientation) 0 1 2 3 4 5 6 7 25 30 35 40 45 50 55 60 65 70 75 80 85 ambient temperature ( ) output current(a) natural convection 100lfm 200lfm 300lfm 400lfm 500lfm 600lfm figure 14: output current vs. ambient temperature and air velocity @vin=48v (transverse orientation, pout2 = 8 w (vout2=3.3v), pout3 = 0.5 w (vout3=5v) dim3r3300(standard) output current vs. ambient temperature and air velocity @vin = 48v; 3.3v&5v=0w (transverse orientation) 0 1 2 3 4 5 6 7 25 30 35 40 45 50 55 60 65 70 75 80 85 ambient temperature ( ) output current(a) natural convection 100lfm figure 15: output current vs. ambient temperature and air velocity @vin=48v (transverse orientation, pout2 = 0 w (vout2=3.3v), pout3 = 0 w (vout3=5v)
