About This Product

■Summary

The MP3424A is a synchronous, high efficiency, current mode step-up (boost) converter with output disconnect. The MP3424A has accurate load current limiting for various load capacitance boosts from the battery input. The MP3424A starts with a low input voltage (VIN) of 2V during inrush current limiting, output short-circuit protection (SCP), and adjustable load current limiting. Integrated P-channel synchronous rectification improves efficiency and eliminates the need for external Schottky diodes. The P-channel MOSFET disconnects the output from the input during shutdown. A 580kHz switching frequency (fSW) allows for small external components, and internal compensation and soft-start reduce external component count. The MP3424A has flexible current limit adjustment from a supply voltage down to 2.8V to a 5V/3.1A load. Delivered in QFN-14 (2mm x 2mm) package.

■Features and benefits

・Wide operating input voltage (VIN) range from 2V to 5.5V ・Output voltage (VOUT) range from 3V to 5.5V ・Supports 5V/3.1A output with 2.8V input ・Linear charge inrush current 270mA ・Current limit switching that can be set up to 9.5A - Configurable average load current limit ・Fixed switching frequency (fSW) of 580kHz ・Up to 97% efficiency ・Internal soft start and correction ・Accurate output load disconnection from input ・Overcurrent protection (OCP) ・Short circuit protection (SCP) ・Overheat protection (OTP) ・Provided in QFN-14 (2mm x 2mm) package ・Optimized with MPS inductor MPL-AL5030 series

■Available product numbers

・MP3424AGG-Z MP3424AGG-P ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
