The MP3423 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnect. The MP3423 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 MP3423 provides a compact solution for a 5V output, 3.1A load requirement, using a supply voltage down to 2.8V. The MP3423 is available in 14-pin QFN 2mmx2mm package.
