IR3801MPbF

SupIRBuck

HIGHLY INTEGRATED 7A

WIDE-INPUT VOLTAGE, SYNCHRONOUS BUCK REGULATOR

Features

Description

•

Wide Input Voltage Range 2.5V to 21V

Wide Output Voltage Range 0.6V to 12V

Continuous 7A Load Capability

600kHz High Frequency Operation

Programmable Over-Current Protection

Hiccup Current Limit

The IR3801 SupIRBuck^TMis an easy-to-use, fully

integrated and highly efficient DC/DC regulator.

The onboard switching controller and MOSFETs

make the IR3801 a space-efficient solution,

providing accurate power delivery for low output

voltage applications.

Precision Reference Voltage (0.6V)

Programmable Soft-Start

The IR3801 operates from a single 4.5V to 14V

input supply and generates an output voltage

adjustable from 0.6V to 0.75*Vin at loads up to 7A.

Pre-Bias Start-up

Thermal Protection

Thermally Enhanced Package

Small Size 5mmx6mm QFN

Pb-Free (RoHS Compliant)

A versatile regulator offering programmability of

startup time, power good threshold and current

limit, the IR3801’s fixed 600kHz switching

frequency allows the use of small external

components.

Applications

•

Game Consoles

The IR3801 also features important protection

functions, such as Pre-Bias startup, hiccup

current limit and thermal shutdown to provide the

required system level security in the event of fault

conditions.
