PD-60332 www.DataSheet4U.com IR3821AMPbF TM SupIRBuck Features • • • • • • • • • • • • • • HIGHLY INTEGRATED 9A Description The IR3821A SupIRBuckTM is an easy-to-use, fully integrated and highly efficient DC/DC regulator. The onboard switching controller and MOSFETs make the IR3821A a space-efficient solution, providing accurate power delivery for low output voltage applications. The IR3821A 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 9A. A versatile regulator offering programmability of startup time, power good threshold and current limit, the IR3821A’s fixed 300kHz switching frequency allows the use of small external components.
