Product Description

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 improves efficiency and eliminates the need for an external Schottky diode.  This P-channel disconnects the output from the input during shutdown. 

The 600kHz switching frequency allows small external components, while the internal compensation and soft-start minimize external component count.  The MP3422 provides a compact solution for a 5V output, 2.5A load requirement, using a supply voltage down to 2.8V.

The MP3422 is available in 14-pin QFN 2mmx2mm package.

6.5A, 600kHz Synchronous Step-up Converter with Output Disconnect Evaluation Board

EV3422-G-00A Evaluation Board is designed to demonstrate the capability of MP3422. MP3422 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnect.

The MP3422 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 MP3422 is available in 14-pin QFN 2mmx2mm package.
