SupIRBuck

12A HIGHLY INTEGRATED

WIDE-INPUT VOLTAGE, SYNCHRONOUS BUCK REGULATOR

Description

Features

The IR3876 SupIRBuck^TMis an easy-to-use,

fully integrated and highly efficient DC/DC

voltage regulator. The onboard constant on time

hysteretic controller and MOSFETs make

IR3876 a space-efficient solution that delivers up

to 12A of precisely controlled output voltage in

60^oC ambient temperature applications without

airflow.

. Input Voltage Range: 3V to 21V

. Output Voltage Range: 0.5V to 12V

. Continuous 12A Load Capability

. Constant On-Time control

. Excellent Efficiency at very low output current levels

. Compensation Loop not Required

. Programmable switching frequency, soft start, and

over current protection

. Power Good Output

. Precision Voltage Reference (0.5V, +/-1%)

. Pre-bias Start Up

. Under/Over Voltage Fault Protection

. Ultra small, low profile 5mm x 6mm QFN Package

Programmable switching frequency, soft start,

and over current protection allows for a very

flexible solution suitable for many different

applications and an ideal choice for battery

powered applications.

Applications

Additional features include pre-bias startup, very

precise 0.5V reference, over/under voltage shut

down, power good output, and enable input with

voltage monitoring capability.

. Notebook and desktop computers

. Game consoles

. Consumer electronics – STB, LCD, TV, printers

. General purpose POL DC-DC converters
