4 / 17 page Model: APA18T04 Series Date: Aug 2005 SH 4 OF 26 Technical Reference Note APA18T04 DC - DC Series ABSOLUTE MAXIMUM RATINGS Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this specification. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability. The converter shall be designed, labeled and safety approved for maximum continuous rating as follows: Parameter Device Symbol Min Typ Max Unit Input Voltage Continuous Transient (100ms) All VIN VIN, trans -0.3 - - - 6 8 Vdc Operating Temperature All Ta -40 - 85 ºC Storage Temperature All TSTG -55 - 125 ºC Operating Humidity All - 10 - 85 % Max Voltage at Enable Pin All - - 12 Vdc Max Output Power All - - 59.4 W 4.3 INPUT SPECIFICATIONS Parameter Device Symbol Min Typ Max Unit Operating Input Voltage Range All VIN 3.0 3.3/5.0 5.5 Vdc Input Under-Voltage Lock-out T_ON Threshold T_OFF Threshold 0.75V=Vo <2.5V 2.7 2.4 2.9 2.6 3.0 2.7 Vdc Input Current (VIN = VIN, Min ; IO = IO, Max) T04 IIN-MAX - - 18.0 A Max Pdiss @ IO = 0A (VIN = VIN, Nom, TA=25°C) Vo:3.3V Vo:0.75V - - - - 0.5 0.3 W Input Ripple Current 1 5Hz to 20MHz All II1 - - 300 mAp-p Input Voltage Rise Time 10% to 90% of Vout All NA - - V/ms Inrush Current dVIN/dt All NA - - Apk NOTE: 1.
