APU3048 - DUAL SYNCHRONOUS PWM CONTROLLER CIRCUITRY AND LDO CONTROLLER
Advanced Power Electronics 2009/04/13 09:23
DESCRIPTION
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 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.
FEATURES
*Dual Synchronous Controller in 16-Pin Package with 1808 out-of-phase operation
*LDO Controller with 40mA drive
*Configured as 2-Independent PWM Controller
*Flexible, Same or Separate Supply Operation
*Operation from 4V to 25V Input
*Internal 200KHz Oscillator
*Soft-Start controls all outputs
*Fixed Frequency Voltage Mode
*500mA Peak Output Drive Capability
*Programmable Outputs
*RoHS Compliant
APPLICATIONS
*DDR Memory Source Sink Vtt Application
*Graphic Card
*Hard Disk Drive
*Power supplies requiring multiple outputs
