MP4321 Datasheet (MPS) - Synchronous Step-Down Converter

MP4321, Synchronous Step-Down Converter

The MP4321 is a configurable-frequency (350kHz to 2.5MHz), synchronous, step-down switching converter with integrated internal highside and low-side power MOSFETs (HS-FET and LS-FET, respectively).

The device provides up to 1A of highly efficient output current (IOUT) with peak current control mode.
