About This Product

■Summary

The MP3424 is a high efficiency synchronous rectifier, current mode, step-up converter with output disconnect. The MP3424 targets boosting various load capacities from a battery input with precise load current limiting. The MP3424 starts from input voltages as low as 2V while providing inrush current limiting, output short-circuit protection (SCP), and programmable load current limiting. An integrated P-channel synchronous rectifier (SR) improves efficiency and eliminates the need for external Schottky diodes. A P-channel MOSFET disconnects the output from the input in shutdown. A fixed switching frequency of 580kHz allows for smaller external components, and internal compensation and soft-start minimize external component count. The MP3424 offers flexible current limit programming for loads up to 5V/3.1A from supply voltages up to 2.8V. The MP3424 is available in a QFN-14 (2mm x 2mm) package.

■Features and benefits

・Input operating range from 2V to 5.5V ・Output range from 3V to 5.5V ・Supports 5V/3.1A output with 2.8V input - Programmable switching current limit up to 9.5A ・Programmable average load current limit ・580kHz fixed frequency switching ・Up to 97% efficiency ・Internal soft start and compensation ・True output disconnection from input ・Over current protection (OCP), short circuit protection (SCP), over temperature protection (OTP) ・Provided in QFN-14 (2mm x 2mm) package

■Available product numbers

・MP3424GG-P MP3424GG-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
