IR3810MPbF

SupIRBuck

HIGHLY INTEGRATED 12A

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 12A Load Capability

600kHz High Frequency Operation

Programmable Over-Current-Protection

Hiccup Current Limit

The IR3810 SupIRBuck^TMis an easy-to-use, fully

integrated and highly efficient DC/DC regulator.

The onboard switching controller and MOSFETs

make the IR3810 a space-efficient solution,

providing accurate power delivery for low output

voltage applications.

Tracking capability for Memory Application

Precision Reference Voltage (0.6V)

Programmable Soft-Start

The IR3810 operates from a 4.5V to 14V input

supply and generates an output voltage

adjustable from 0.6V to 0.80*Vin at loads up to

12A.

Pre-Bias Start-up

Thermal Protection

Thermally Enhanced Package

Small Size 5mmx6mm QFN

IR3810 can be configured for tracking

applications to generate termination voltage (VTT)

for memory applications.

Pb-Free (RoHS Compliant)

Applications

A versatile regulator offering programmability of

start up time and current limit, the IR3810’s fixed

600kHz switching frequency allows the use of

small external components.

•

Distributed Point-of-Loads

Server and Workstations

Embedded Systems

Storage Systems

IR3810 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.

DDR Applications

Graphics Cards

Game Consoles

Computing Peripheral Voltage Regulators
