BASIC APPLICATION

Figure 1: IR3473 Basic Application Circuit

DESCRIPTION

The IR3473 SupIRBuck

TM is an easy‐to‐use, fully integrated

and highly efficient DC/DC voltage regulator. The onboard

constant on time hysteretic controller and MOSFETs make

IR3473 a space‐efficient solution that delivers up to 6A of

precisely controlled output voltage.

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.

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.

APPLICATIONS

• 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
