DESCRIPTION
The APU3048 IC combines a Dual synchronous Buck
controller and a linear regulator controller, providing a cost-
ffective, high performance and flexible solution for multi-
output applications. The Dual synchronous controller is
configured as 2-independent PWM controller. APU3048
provides a separate adjustable output by driving 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 function as
well as output under-voltage detection that latches off the
device when an output short is detected.
APPLICATIONS
DDR Memory Source Sink Vtt Application
Graphic Card
Hard Disk Drive
Power supplies requiring multiple outputs
