MP3424AGG-P

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 (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 shutdown. The 580KHz switching frequency allows for small external components, while internal compensation and soft start minimize the external component count. The MP3424A is available in a QFN-14 (2mmx2mm) package. Applications include battery powered products, power banks, juice packs, battery backup units, optical modules, USB power supplies and consumer electronic accessories.
