IRU3039(PbF)

SYNCHRONOUS PWM CONTROLLER

WITH OVER CURRENT PROTECTION

FEATURES

DESCRIPTION

Current Limit using Lower MOSFET Sensing

The IRU3039 controller IC is designed to provide a syn-

Using the 6V internal regulator for charge pump

circuit allows single supply operation up to 18V

chronous Buck regulator and is targeted for applications

where the cost and size is critical. The IRU3039 oper-

Programmable Switching Frequency up to 400KHz ates with a single input supply up to 18V. The output

Soft-Start Function

voltage can be programmed as low as 0.8V for low volt-

age applications. Selectable current limit is provided to

tailor to external MOSFET’s on-resistance for optimum

cost and performance. The IRU3039 features an uncom-

mitted error amplifier for tracking output voltage and is

capable of sourcing or sinking current for applications

such as DDR bus termination.

APPLICATIONS

DDR Memory VDDQ/VTT Applications

Graphic Card

This device features a programmable switching frequency

set from 200KHz to 400KHz, under-voltage lockout for

both Vcc and Vc supplies, an external programmable

soft-start function as well as output under-voltage detec-

tion that latches off the device when an output short is

detected.
