The IR3822A SupIRBuckTM is an easy-to-use, fully integrated and highly efficient DC/DC regulator. The onboard switching controller and MOSFETs make the IR3822A a space-efficient solution, providing accurate power delivery for low output voltage applications. The IR3822A operates from a single 4.5V to 14V input supply and generates an output voltage adjustable from 0.6V to 0.8*Vin at loads up to 6A. A versatile regulator offering programmability of startup time, power good threshold and current limit, the IR3822A's fixed 300kHz switching frequency allows the use of small external components.
