DESCRIPTION

The MP8670 is a monolithic step-down switch

mode converter with a built-in internal power

MOSFET. It achieves 6A continuous output

current over a wide input supply range with

excellent load and line regulation.

Current mode operation provides fast transient

response and reliable over-current protection.

The MP8670 requires a minimum number of

readily available standard external components

and is available in an 8-pin SOIC package with

exposed pad.
