FP5451A
DUAL CHANNEL PWM CONTROL IC WITH SCP/DTC FUNCTION
GENERAL DESCRIPTION
The FP5451A, a 1-chip composed of dual open collector
transistor pulse-width-modulation control circuits with two error amplifiers and dead-time comparators (DTC), the FP5451A 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, FP5451A, a high performance integrated IC, is designed for a control circuit.
The circuit diagram of the typical application example is as ...
