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 IR3821MPbF SupIRBuck is an easy-to-use, fully integrated and highly efficient DC/DC regulator. The onboard switching controller and MOSFETs make the IR3821 a space-efficient solution, providing accurate power delivery for low output voltage applications.

The IR3821MPbF operates from a single 4.5V to 14V input supply and generates an output voltage adjustable from 0.6V to 0.75*Vin at loads up to 7A.A versatile regulator offering programmability of startup time, power good threshold and current limit, the IR3821's fixed 600kHz switching frequency allows the use of small external components. 

The IR3821MPbF 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.
