Caution: Stresses beyond those listed under "Absolute Maxmum Rating"may cause permanent damage to the device. These are stress ratings only and functional operation  of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to "Absolute Maximum Rating"conditions for extended periods may affect device reliability

The IR3821AMPbF SupIRBuck^TM 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 IR3821AMPbF 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. 

The IR3821AMPbF 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.
