MP3424GG-P Monolithic Power Systems

MP3424 Current Programmable, CC/CV, Synchronous, Step-Up Converter with Output Disconnect The Future of Analog IC Technology DESCRIPTION FEATURES 2V to 5.5V Input Work Range The MP3424 is a high-efficiency, synchronous, 3V to 5.5V Output Range current-mode, step-up converter with output Supports 5V/3.1A Output from 2.8V Input disconnect. The MP3424 targets various load capability boosts from a battery input with an Programmable up to 9.5A Switching Current accurate load current limit. Limit Programmable Average Load Current Limit The MP3424 starts up from an input voltage as 580kHz Fixed Frequency Switching low as 2V while providing inrush current limiting, Up to 97% Efficiency output short-circuit protection (SCP), and Internal Soft Start and Compensation programmable load current limit. The integrated True Output Load Disconnect from Input P-channel synchronous rectifier improves Over-Current Protection (OCP), Short- efficiency and eliminates the need for an Circuit Protection (SCP), and Over- external Schottky diode. The P-channel Temperature Protection (OTP) MOSFET disconnects the output from the input Available in a QFN-14 (2mmx2mm) during shutdown. Package The 580kHz switching frequency allows for small external components, while internal APPLICATIONS compensation and soft-start minimize the Battery-Powered Products external component count. The MP3424 Power Bank, Juice Packs, Battery Back-Up provides flexible current limit programming for Units up to 5V/3.1A load from a supply voltage down Electronic Cigarettes to 2.8V. USB Power Supplies The MP3424 is available in a QFN-14 Consumer Electronic Accessories (2mmx2mm) package. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
