Description

EV3424-G-00A Evaluation Board is designed to demonstrate the capability of MP3424. MP3424 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnect. The MP3424 starts up from an input voltage as low as 2V, while providing inrush current limiting, output short-circuit protection, and programmable load current limit. The integrated P-channel, synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode. The P-channel MOSFET disconnects the output from the input during shutdown. The 580kHz switching frequency allows small external components, while the internal compensation and soft-start minimize external component count. The MP3424 provides flexible current limit program for up to 5V/3.1A load from a supply voltage down to 2.8V.The MP3424 is available in 14-pin QFN 2mmx2mm package.
