Monolithic Power Systems (MPS) MP3424A Synchronous Step-Up Converter

Monolithic Power Systems (MPS) MP3424A Synchronous Step-Up Converter is a high-efficiency, current mode, boost converter with output disconnect. The MP3424A targets various load capability boosts from a battery input with an accurate load current limit. The MP3424A starts up from an input voltage (VIN) as low as 2V while providing inrush current limiting, output short-circuit protection (SCP), and a configurable 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 a shutdown.

The MP3424A has a 580kHz fixed switching frequency (fSW), allowing for small external components, while internal compensation and soft-start minimize the external component count. The MP3424A provides flexible current limit programming for up to a 5V, 3.1A load from a supply voltage down to 2.8V.

The Monolithic Power Systems (MPS) MP3424A Synchronous Step-Up Converter is available in a compact QFN-14 package ideal for space-constrained applications.
