NEC 4“PC1100,u.PC1150 DUAL SWITCHING REGULATOR CONTROL CIRCUIT

DESCRIPTION

The uPC1100, PC1150 are PWM type dual switching regulator control circuits which incorporate 2.5 V 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. The uPC1100, uPC1150 feature low supply voltage operation, low stand- by 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 available in accordance with short protection method.

FEATURES

@ Two outputs synchronized operation © Wide supply voltage range 3.6 V < Voc $40 V @ Lowstand-by and supply current stand-by mode; 2.2 mA, operation mode; 2.5mA @ Timer latch short protection circuit @ uPC1100 — Two outputs cut off when one channel becomes short state. @ yuPC1150 — Only short channel cuts off. @ Internal ON/OFF control circuit
