IR3822AMPbF

SupIRBuck

HIGHLY INTEGRATED 6A

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 6A Load Capability

300kHz High Frequency Operation

Programmable Over-Current Protection

Programmable PGood Output

Hiccup Current Limit

The IR3822A SupIRBuck^TMis an easy-to-use,

fully integrated and highly efficient DC/DC

regulator. The onboard switching controller and

MOSFETs make the IR3822A a space-efficient

solution, providing accurate power delivery for

low output voltage applications.

Precision Reference Voltage (0.6V)

Programmable Soft-Start

The IR3822A operates from a single 4.5V to 14V

input supply and generates an output voltage

adjustable from 0.6V to 0.8*Vin at loads up to 6A.

Pre-Bias Start-up

Thermal Protection

A versatile regulator offering programmability of

startup time, power good threshold and current

limit, the IR3822A’s fixed 300kHz switching

frequency allows the use of small external

components.

Thermally Enhanced Package

Small Size 5mmx6mm QFN

Pb-Free (RoHS Compliant)

Applications

•

Distributed Point-of-Loads

Server and Workstations

Embedded Systems

The IR3822A 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.
