MP3424A

Current-Configurable, CC/CV, Synchronous Step-Up Converter with Output Disconnect and Minimized Inrush Current

MPL

Description

MPL

Optimized Performance with MPS Inductor

The MP3424A is a synchronous, high-efficiency, current mode, step-up (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 (V_IN) 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 (SR) 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 (f_SW) allows for small external components, while internal compensation and soft start reduce the external component count.

The MP3424A provides flexible current limit configurations up to a 5V/3.1A load from a supply voltage down to 2.8V. It is available in a QFN-14 (2mmx2mm) package.

Optimized Performance with MPS Inductor

The EVL3424A-G-00A is an evaluation board designed to demonstrate the capabilities of the MP3424A, a high-efficiency, current-mode, synchronous step-up converter with output disconnect.

The MP3424A provides inrush current limiting, output short-circuit protection (SCP), and a configurable load current limit. The integrated P-channel synchronous rectifier (SR) improves efficiency and eliminates the need for an external Schottky diode. During shutdown, the P-channel MOSFET disconnects the output from the input.

The 580kHz switching frequency (f_SW) allows for small external components, while internal compensation and soft start (SS) minimize the number of external components. The MP3424A is available in a QFN-14 (2mmx2mm) package.
