Description

The LT1371HVCSW is a monolithic high frequency current mode switching regulator. It can be operated in all standard switching configurations including boost, buck, flyback,forward, inverting and "Cuk." A 3A high efficiency switch is included on the die, along with all oscillator, control and protection circuitry.

Features of the LT1371HVCSW are:(1)faster switching with increased efficiency;(2)uses small inductors: 4.7H;(3)all surface mount components;(4)low minimum supply voltage: 2.7V;(5)quiescent current: 4mA Typ;(6)current limited power switch: 3A;(7)regulates positive or negative outputs;(8)shutdown supply current: 12mA Typ;(9)easy external synchronization.Applications of the LT1371HVCSW are:(1)boost regulators;(2)laptop computer supplies;(3)multiple output flyback supplies;(4)inverting supplies.

The absolute maximum ratings of the LT1371HVCSW can be summarized as:(1):the parameter is supply voltage,the rating is 30,the unit is V;(2):the parameter is switch voltage,the rating is 42,the unit is V;(3):the parameter is S/S, SHDN, SYNC pin voltage,the rating is 30,the unit is V;(4):the parameter is feedback pin voltage (transient, 10ms),the rating is ±10,the unit is V;(5):the parameter is feedback pin current,the rating is 10,the unit is mA;(6):the parameter is negative feedback pin voltage (transient, 10ms),the rating is ±10,the unit is V;(7):the parameter is operating ambient temperature range,the rating is 0 to 70,the unit is ;(8):the parameter is operating junction temperature range commercial,the rating is 0 to 125,the unit is ;(9):the parameter is operating junction temperature range industrial,the rating is -40 to 125,the unit is ;(10):the parameter is operating junction temperature range short circuit,the rating is 0 to 150,the unit is ;(11):the parameter is storage temperature range,the rating is -65 to 150,the unit is ;(12):the parameter is lead temperature (soldering,10 sec),the rating is 300,the unit is .
