FP5453-DUAL PWM CONTROL IC SHORT CIRCUIT RESTART


FP5453 DUAL PWM CONTROL IC WITH SHORT CIRCUIT RESTART FUNCTION
General Description
Download
 The FP5453, a 1-chip composed of totem-pole output stage pulse-width-modulation control circuits with two error amplifiers and dead-time comparators (DTC), the FP5453 contains a 2.5V precision voltage reference regulator, under-voltage lockout circuit (UVLO), programmable auto-restart timer for short circuit protection (SCSAR), applied to offer space and low cost in many applications such as the DC/DC converter.
 Using few external components, FP5453, a high performance integrated IC, is designed for a control circuit. The circuit diagram of the typical application example is as below.
