Page 4 Isolation Specifications Parameter Symbol Min Typ Max Unit Isolation Capacitance Ciso 1000 pF Isolation Resistance Riso 10 MΩ Feature Specifications Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions. See Feature Descriptions for additional information. Parameter Device Symbol Min Typ Max Unit Remote On/Off Signal Interface (VIN=VIN, min to VIN, max , Signal referenced to VIN- terminal) Negative Logic: device code suffix “1” Logic LO = module On, Logic HI = module Off Positive Logic: No device code suffix required Logic LO = module Off, Logic HI = module On Logic LO Specification On/Off Thresholds: Remote On/Off Current – Logic LO (Vin =100V) All Ion/off 280 310 μA Logic LO Voltage All Von/off -0.3 0.8 Vdc Logic HI Voltage – (Typ = Open Collector) All Von/off 2.0 14.5 Vdc Logic HI maximum allowable leakage current (Von/off = 2.0V) All Ion/off 10 μA Maximum voltage allowed on On/Off pin All Von/off 14.5 Vdc TON_DELAY and TON_RISE (Adjustable via PMBus) Tdelay=Time until VO = 10% of VO,set from either application of Vin with Remote On/Off set to On (Enable with Vin); or operation of Remote On/Off from Off to On with Vin already applied for at least 150 milli-seconds (Enable with on/off). (IO=IO, max) * Increased Tdelay due to startup for parallel modules. All w/o -P Tdelay , Enable with Vin 150 ms All w/o-P Tdelay, Enable with on/off 10 ms w/ -P Tdelay, Enable with Vin 180* ms w/ -P Tdelay, Enable with on/off 40* ms Trise=Time for VO to rise from 10% to 90% of VO,set, For CO >5000uF, IO must be < 50% IO, max during Trise. * Increased Trise when Vo exists at startup for parallel modules. All w/o - P Trise 15 ms w/ -P Trise 300* ms Load Sharing Current Balance (difference in output current across all modules with outputs in parallel, no load to full load) -P Option Idiff 3 A Remote Sense Range All VSense 0.5 Vdc VOUT_COMMAND (Adjustable via PMBus) All VO, set 8.1 13.2 Vdc VOUT_OV_FAULT_LIMIT (Adjustable via PMBus) All VO,limit VO,set- +2.5V VO,set- +5.0V Vdc OT_FAULT_LIMIT (Adjustable via PMBus) All Tref 140 °C Input Undervoltage Lockout (Adjustable via PMBus) VIN_ON 33 35 36 Vdc VIN_OFF 31 33 34 Vdc Input Overvoltage Lockout (Adjustable via PMBus) Turn-off Threshold [VIN_OV_FAULT_LIMIT] 85 Vdc Turn-on Threshold (follows VIN_OV_FAULT_LIMIT -7V) 78 Vdc Pull down resistance of PGOOD pin Sink current capability into PGOOD pin (VPG=2.2V) All All 150 15 Ω mA |
