UPC1150C

he UPC1150C is PWM type dual switching regulator control circuits which incorporate 2.5V voltage reference,variable frequency oscillator,two sets of synchronized switching control circuits,timer latch short protection circuit and ON/OFF control circuit on a single monolithic chip.It feature low supply voltage operation,low standby current and low supply current therefore,these ICS are the optimum choise for battery operated portable equipments power supply and other DC-DC converter applications.Two ICs are avaliable in accordance with short protection method.

Features of the UPC1150C are:(1)two outputs synchronized operation;(2)wide supplu voltage range 3.6VVCC40V;(3)low stand-by and supply current stand-by mode,2.2mA,operation mode,2.5mA;(4)timer latch short protection circuit;(5)only short channel cuts off;(6)internal ON/OFF control circuit.

The absolute maximum ratings of the UPC1150C can be summarized as:(1)DC supply voltage,VCC:41V;(2)error amplifier input voltage,Vi:20V;(3)total power dissipation C package,Pt1:1000mW;(4)operating tempreature,Topt:-20 to +85;(5)storage temperature,Tstg:-55 to +150;(6)output voltage,VO:41V;(7)output current,IO:25mA;(8)total power dissipation GS package,Pt2:694mW.
