| MP1010B Cold Cathode Fluorescent Lamp Driver The Future of Analog IC Technology DESCRIPTION The MP1010B is a power solution IC that offers a true complete solution for driving a Cold Cathode Fluorescent Lamps (CCFL). This Power IC converts unregulated DC voltage to a nearly pure sine wave required to ignite and operate the CCFL. Based on proprietary power topology and control techniques it greatly increases the power conversion efficiency. FEATURES * * * * * * * * * * * * * Integrated Power Switches 6.0V to 23V Variable Supply Voltage with Regulated Lamp Current. Rated 12W Power Output at 12V Input Open Lamp Regulation Current and Voltage Feedback Control Logic Level Burst Mode Control Supports Open/Short Lamp Protection Soft-Start Short Circuit Protected Output High Energy Start Pulse Analog and Burst Mode Dimming EVALUATION BOARD REFERENCE Board Number EV0037 Dimensions 4.0"X x 0.5"Y x 0.4"Z APPLICATIONS LCD Backlight Inverter for Notebook Computers Web Pads, GPS, Desktop Displays, Portable DVD, Car Video Display Systems "MPS" and "The Future of Analog IC Technology" are Registered Trademarks of Monolithic Power Systems, Inc.
