DUAL SYNCHRONOUS PWM CONTROLLER

CIRCUITRY AND LDO CONTROLLER

PRELIMINARY DATA SHEET

DESCRIPTION

FEATURES

Dual Synchronous Controller in 16-Pin Package

with 1808 out-of-phase operation

The APU3048 IC combines a Dual synchronous Buck

controller and a linear regulator controller, providing a

cost-effective, high performance and flexible solution for

multi-output applications. The Dual synchronous con-

troller is configured as 2-independent PWM controller.

APU3048 provides a separate adjustable output by driv-

ing a switch as a linear regulator. This device features an

internal 200KHz oscillator, under-voltage lockout for all

input supplies, an external programmable soft start func-

tion as well as output under-voltage detection that latches

off the device when an output short is detected.

LDO Controller with 40mA drive
