DESCRIPTION

The MP8768 is a high frequency synchronous

rectified step-down switch mode converter with

a built in internal high side power MOSFET. It

offers a very compact solution to achieve 8A

continuous output current over a wide input

supply range with excellent load and line

regulation.

The

MP8768

has

very

high

efficiency over a wide output load range.

Current mode operation provides fast transient

response and eases loop stabilization.

Full protection features include OCP and thermal

shut down.

The MP8768 requires a minimum number of

readily available standard external components

and is available in a space saving 3mm x 4mm

14-pin QFN package.
