The Future of Analog IC Technology DESCRIPTION The MP3424 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnect. The MP3424 targets various load capability boosts from a battery input with an accurate load current limit. The MP3424 starts up from an input voltage as low as 2V while providing inrush current limiting, output short-circuit protection (SCP), 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 for small external components, while internal compensation and soft-start minimize the external component count.
