FP5352
PHASE SHIFT DUAL PWM IC
WITH SCP/OVP FUNCTION
GENERAL DESCRIPTION
The FP5352, an 1-chip composed of dual channel phase shift 180 totem-pole output stage
pulse-width-modulation control circuits with two independent error amplifiers for step-down
converter application, the inverting input of amplifier connects to a 1.0V precision reference
regulator, power down under-voltage lockout circuit (UVLO), short circuit and over voltage
shutdown and auto-restart protection circuit (SCP/OVP) and dead-time control circuit (DTC),
applied to offer the space and low cost in many applications of PC peripherals .
FEATURES
Internal EA Bias Reference Voltage: 1.0V
Reference Voltage Precision: 2%
