MP2321 Datasheet Constant-On-Time Step-Down Converter

Manufacturer: Monolithic Power Systems

General Description

The MP2321 is a fully-integrated, highefficiency, synchronous, step-down, switchmode converter with 40μA of quiescent current.

The MP2321 achieves 2A of continuous output current over a wide input supply range with excellent load and line regulation and can operate with high efficiency over a wide output current load range.

The MP2321 is optimized for battery-operated applications and applications requiring high light-load efficiency.

Overview
