MP3424

Current Programmable, CC/CV, Synchronous, Step-Up Converter with Output Disconnect

Datasheet

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. The MP3424 provides flexible current limit programming for up to 5V/3.1A load from a supply voltage down to 2.8V.
The MP3424 is available in a QFN-14 (2mmx2mm) package.
