IR3822MPBF General Description

The IR3822 SupIRBuck^TM is an easy-to-use, fully integrated and highly efficient DC/DC regulator. The onboard switching controller and MOSFETs make the IR3822 a space-efficient solution, providing accurate power delivery for low output voltage applications.

The IR3822 operates from a 4.5V to 14V input supply and generates an output voltage adjustable from 0.6V to 0.75*Vin at loads up to 4A.

A versatile regulator offering programmability of startup time, power good threshold and current limit, the IR3822's fixed 600kHz switching frequency allows the use of small external components.

The IR3822 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.
