4 / 16 page Data Sheet March 27, 2008 QBK025A0B DC-DC Power Modules: 36-55Vdc Input; 12Vdc Output Voltage; 25A Output Current LINEAGE POWER 4 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 Low = module On, Logic High = module Off Positive Logic: No device code suffix required Logic Low = module Off, Logic High = module On On/Off Thresholds: Remote On/Off Current – Logic Low All Ion/off 5 10 15 μA Logic Low Voltage All Von/off 0.0 ⎯ 0.8 V Logic High Voltage – (Typ = Open Collector) All Von/off 2.0 ⎯ 5.0 V Logic High maximum allowable leakage current (Von/off = 2.0V) All Ion/off ⎯ ⎯ 6.0 μA Maximum voltage allowed on On/Off pin All Von/off ⎯ ⎯ 14.0 V Turn-On Delay and Rise Times (IO= IO, max , VIN=VIN, nom, TA = 25 oC) Case 1: Time until VO = 10% of VO,set from application of Vin with Remote On/Off set to On 12 Tdelay Enable with Vin ― 15 ― msec Case 2: Time until VO = 10% of VO,set from operation of Remote On/Off from Off to On with Vin already applied for at least one second. Tdelay Enable with on/off ― 1.5 ― msec Output Voltage Rise time (time for Vo to rise from 10% of Vo, set to 90% of Vo, set) Trise ― 1 ― msec Over Temperature Protection All Tref ⎯ 125 ⎯ °C (See Thermal Considerations section) Input Under Voltage Lockout VUVLO Turn-on Threshold ⎯ 35 36 V Turn-off Threshold 32 34 ⎯ V Over Voltage Protection 12V 13 ⎯ 15 V |
