IRU3046

DUAL SYNCHRONOUS PWM CONTROLLER WITH

CURRENT SHARING CIRCUITRY AND LDO CONTROLLER

PRELIMINARY DATA SHEET

FEATURES

DESCRIPTION

The IRU3046 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 24-Pin Package

with 1808 out-of-phase operation

LDO Controller with Independent Bias Supply

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 IRU3046 provides

ration

a programmable current sharing which is ideal when the

output power exceeds any single input power budget.

IRU3046 provides a separate adjustable output by driv-

Flexible, Same or Separate Supply Operation

Operation from 4V to 25V Input

Programmable Switching Frequency up to 400KHz ing a switch as a linear regulator. This device features

Soft-Start controls all outputs

programmable switching frequency up to 400KHz per

phase, under-voltage lockout for all input supplies, an

external programmable soft-start function as well as out-

put under-voltage detection that latches off the device

when an output short is detected.

Precision Reference Voltage Available

500mA Peak Output Drive Capability

Short Circuit Protection for all outputs

Power Good Output

Synchronizable with External Clock
