IR3811MPbF

The IR3811MPbF is an easy-to-use, fully integrated and highly efficient DC/DC regulator. The onboard switching controller and MOSFETs make the IR3811 a space-efficient solution, providing accurate power delivery for low output voltage applications.

The IR3811MPbF operates from a 4.5V to 14V input supply and generates an output voltage adjustable from 0.6V to 0.80*Vin at loads up to 7A.

IR3811MPbF can be configured for tracking applications to generate termination voltage (VTT) for memory applications.

A versatile regulator offering programmability of start up time and current limit, the IR3811's fixed 600kHz switching frequency allows the use of small external components. IR3811 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.
