SLVS868 – MARCH 2009 INTEGRATED PHOTO FLASH CHARGER AND IGBT DRIVER FEATURES 1 2 Wide Input Voltage – VBAT = 1.4 V to 12 V – VCC = 2.5 V to 5.5 V Integrated 50-V Power Switch With Lower RON Programmable Peak Current at Primary Side From 0.5 A to 1.5 A Optimized Switch ON/OFF Control for Fast Charging Charge Complete Detection at Primary Side With High Accuracy Integrated IGBT Driver 2-mm × 3-mm, 12-Pin WSON Package Protection – Overcurrent Protection (OCP) – Thermal Shutdown (TSD) APPLICATIONS Digital Still Cameras Optical Film Cameras Digital Video Camcorders Cell Phones DESCRIPTION/ORDERING INFORMATION The TPS65573 offers a complete solution for a charging photo flash capacitor and flashing xenon tube with insulated gate bipolar transfer (IGBT) driver. This device has an integrated voltage reference, power (SW), comparators for peak current detection/power SW turnon detection/charge complete detection, IGBT driver and control logics for charging applications/driving IGBT applications. Compared with discrete solutions, this device reduces the component count, shrinks the total solution size, and erases the difficulty of design for xenon tube application. Additional advantages are a fast charging time and h...
