GENERAL DESCRIPTION
FP1451
DUAL CHANNEL PWM CONTROL IC
WITH SCP/DTC FUNCTION
The FP1451, a 1-chip composed of dual open collector transistor pulse-width-modulation
control circuits with two error amplifiers and dead-time comparators (DTC), the FP1451
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, FP1451, a high performance integrated IC, is designed for a
control circuit. The circuit diagram of the typical application example is as below.
