MP3422 Datasheet (MPS) - Synchronous Step-Up Converter

MP3422, Synchronous Step-Up Converter

The MP3422 is a high-efficiency, synchronous, current *mode, step-up converter with output disconnect.

The MP3422 starts up from an input voltage as low as 1.9V, while providing inrush current limiting and output short-circuit protection.

The integrated P-channel synchronous rectifier improve
