IRU3047

DUAL SYNCHRONOUS PWM CONTROLLER WITH

CURRENT SHARING CIRCUITRY AND LDO CONTROLLER

PRELIMINARY DATA SHEET

FEATURES

DESCRIPTION

The IRU3047 IC combines a Dual synchronous Buck

controller and a linear regulator controller, providing a

cost-effective, high performance and flexible solution for

Dual Synchronous Controller in 20-Pin Package

with 1808 out-of-phase operation

LDO Controller with 40mA drive

Can be configured as 2-Independent or 2-Phase multi-output applications. The Dual synchronous con-

PWM Controller troller can be configured as 2-independent or 2-phase

Programmable Current Sharing in 2-Phase Configu- controller. In 2-phase configuration, the IRU3047 provides

ration

a programmable current sharing which is ideal when the

output power exceeds any single input power budget.

IRU3047 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.

Flexible, Same or Separate Supply Operation

Operation from 4V to 25V Input

Internal 200KHz Oscillator per phase

Soft-Start controls all outputs
