Description

General part information

MP3422 Series

The MP3422 is a high-efficiency, synchronous, current–mode, step-up converter with output disconnect. The MP3422 can start up from an input voltage as low as 1.9V while provide inrush current limiting, and output short-circuit protection. 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 component, while the internal compensation and soft-start minimize external component count. The MP3422 provides small size solution for 5V/2.5A load from a supply voltage down to 2.8V. The MP3422 is available in 14-pin QFN 2mmx2mm package
