Product Summary
The FP5451ADR is a dual channel PWM control IC with SCP/DTC function. It is composed of dual open collector transistor pulse-width-modulation control circuits with two error amplifiers and dead-time comparators (DTC), the FP5451ADR contains a 2.5V precision voltage reference regulator, under-voltage lockout circuit (UVLO), short circuit protection circuit (SCP), applied to offer space and low cost in many applications such as the DC/DC converter and backlight inverter. Using few external components, FP5451ADR, a high performance integrated IC, is designed for a control circuit. The circuit diagram of the typical application example is as below. The applications of the FP5451ADR include Dual Output Switch Regulator, Backlight Inverter, and LCD Monitor.
