www.DataSheet.co.kr MP1048 Full Bridge CCFL Controller The Future of Analog IC Technology DESCRIPTION The MP1048 is a fixed operating frequency inverter controller that controls four external N-Channel power MOSFETs in a full-bridge configuration. The inverter is designed to power up to 6 cold cathode fluorescent lamps (CCFLs) to backlight liquid crystal displays. Its full-bridge architecture converts unregulated DC input voltages to the nearly pure sine waves required to ignite and operate CCFLs. For reliable lamp ignition, the operating frequency is set by an external resistor and during startup is temporarily swept toward the unloaded resonant frequency of the tank. Burst mode or analog mode dimming are controlled with an external analog signal. Built-in fault management features incl [ ... ]
