MP3120 - MPS

MP3120 1.1MHz Synchronous Boost Converter

The MP3120 is a high efficiency synchronous, current mode step-up converter. The device can boost a single cell or two cells AA battery up to 5V. The MP3120 can start up from an input voltage as low as 0.8V and provide in-rush current limiting as well as output short circuit protection. The integrated P-Channel synchronous rectified switch provides improved .

Features
