MP3421

The EV3421-G-00A evaluation board is designed to demonstrate the capability of the MP3421. The MP3421 is a high-efficiency, synchronous, current mode, step-up converter with output disconnect.

The MP3421 can provide inrush current limiting and output short-circuit protection. It can work with an input voltage as low as 1.9V. The integrated P-channel synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode. The PMOS disconnects the output from the input when the part shuts down.

The 600kHz switching frequency allows for small external components, while the internal compensation and soft start minimize the external component count. The MP3421 is available in a QFN-14 (2mmx2mm) package.
