MP3422 6.5A, 600kHz High Efficiency, Synchronous Step-Up Converter with Output Disconnect in 2x2mm QFN Package The Future of Analog IC Technology DESCRIPTION FEATURES The MP3422 is a high-efficiency, synchronous, Up to 98% Efficiency currentmode, step-up converter with output 1.9V to 5.5V Input Range disconnect. 2.5V to 5.5V Output Range The MP3422 starts up from an input voltage as Internal Synchronous Rectifier low as 1.9V, while providing inrush current 600kHz Fixed Switching Frequency limiting and output short-circuit protection. The >6.5A Switch Current Limit Capability integrated P-channel synchronous rectifier 43uA Quiescent Current improves efficiency and eliminates the need for High Efficiency over Full Load Range an external Schottky diode. This P-channel Internal Soft-start and Compensation disconnects the output from the input during True Output Load Disconnect from Input shutdown. OCP, SCP, OVP and OTP Protection The 600kHz switching frequency allows small Small 2x2mm QFN14 Package external components, while the internal APPLICATIONS compensation and soft-start minimize external component count. The MP3422 provides a Battery-Powered Products compact solution for a 5V output, 2.5A load Power Banks, Juice Packs, Battery Back-up requirement, using a supply voltage down to Units 2.8V. USB Power Supply Consumer Electronic Accessories The MP3422 is available in 14-pin QFN Tablets 2mmx2mm package. All MPS parts are lead-free and adhere to the RoHS directive.
