FP5453

Technology FP5453 DUAL PWM CONTROL IC WITH SHORT CIRCUIT RESTART FUNCTION GENERAL DESCRIPTION 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. FEATURES Fixed Reference Voltage: 2.5V Reference Voltage Precision: 2% Totem-pole output stage Low quiescent supply current under 4mA Wide operating voltage range: 3.6~25V Variable dead-time control (DTC) UVLO protection function Short circuit shutdown/auto re-start function (SCSAR) Oscillator Frequency: Max....
