MP3351 60V, 2A Integrated Photo Flash Charger With IGBT Driver The Future of Analog IC Technology DESCRIPTION FEATURES The MP3351 is a fast, highly efficient, precision Integrated 60V, 200m Power Switch high voltage photo-flash charger with integrated Operates from a Single or Duel-Cell Li+ Battery IGBT driver for xenon flash applications. The 2A peak current w/resistor program programmable peak current from 300mA to 2A. 3% Charge Accuracy A 200m internal power switch minimizes the Integrated IGBT Driver conduction loss. 60V maximum output voltage lowers the transformer turns ratio and improves APPLICATIONS switching loss associated with the primary Digital Still Cameras leakage inductance. External feedback provides Optical Film Cameras 3% charge accuracy. Mobile Phones With Camera The MP3351 is available in a 16-pin 3mm x PDAs With Camera 3mm QFN package MPS and The Future of Analog IC Technology are Registered Trademarks of Monolithic Power Systems, Inc.
