MP8676DN - 420kHz Step-Down Converter

Download the MP8676DN datasheet PDF. This datasheet also covers the MP8676 variant, as both devices belong to the same 420khz step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP8676 is a monolithic step-down switch mode converter with a built in internal power MOSFET.

It achieves 4.5A continuous output current over a wide input supply range with excellent load and line regulation.

Current mode operation provides fast transient response and eases loop stabilization.
