MP3422
MP3422 is Synchronous Step-Up Converter manufactured by Monolithic Power Systems.
The Future of Analog IC Technology
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 600k Hz switching frequency allows small external ponents, while the internal pensation and soft-start minimize external ponent count. The MP3422 provides a pact 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.
