12A Highly Integrated SupIRBuck^TM

IR3476

FEATURES

DESCRIPTION

The IR3476 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

IR3476 a space-efficient solution that delivers up to 12A of

precisely controlled output voltage.

 Input Voltage Range: 3V to 27V

 Output Voltage Range: 0.5V to 12V

 Continuous 12A Load Capability

 Constant On-Time Control

Programmable switching frequency, soft start, and

thermally compensated over current protection allows for

a very flexible solution suitable for many different

applications and an ideal choice for battery powered

applications.

 Compensation Loop not Required

 Excellent Efficiency at Very Low Output Currents

 Programmable Switching Frequency and Soft Start

 Thermally Compensated Over Current Protection

 Power Good Output

Additional features include pre-bias startup, very precise

0.5V reference, under/over voltage shutdown, thermal

protection, power good output, and enable input with

voltage monitoring capability.

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

 Enable Input with Voltage Monitoring Capability

 Pre-bias Start Up

 Thermal Shut Down

APPLICATIONS

 Under/Over Voltage Fault Protection

 Forced Continuous Conduction Mode Option

 Small, Low Profile 5mm x 6mm QFN Package

 Notebook and Desktop Computers

 Consumer Electronics – STB, LCD, TV, Printers

 12V and 24V Distributed Power Systems

 General Purpose POL DC-DC Converters

 Game Consoles and Graphics Cards
