Description
General part information
MP3423 Series
The MP3423 is a high-efficiency, synchronous, current-mode, step-up converter with output disconnect. The MP3423 starts up from an input voltage as low as 1.9V, while providing inrush current limiting and output short-circuit protection. The integrated P-channel synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode. This P-channel disconnects the output from the input during shutdown. The 600kHz switching frequency allows small external components, while the internal compensation and soft-start minimize external component count. The MP3423 provides a compact solution for a 5V output, 3.1A load requirement, using a supply voltage down to 2.8V. The MP3423 is available in 14-pin QFN 2mmx2mm package.Up to 98% Efficiency 1.9V to 5.5V Input Range 2.5V to 5.5V Output Range Internal Synchronous Rectifier 600kHz Fixed Switching Frequency 9A Typical Switch Current Limit 43uA Quiescent Current High Efficiency over Full Load Range Internal Soft-start and Compensation True Output Load Disconnect from Input OCP, SCP, OVP and OTP Protection Small 2x2mm QFN14 Package
