DOINNMTPOESTRPDNIRASELTLIRUIMSBIEUNTAOERNYLYSPEC Monolithic Power Systems MP1038 Full Bridge CCFL Controller PRELIMINARY RELEASE – MPS CONFIDENTIAL DESCRIPTION The MP1038 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 one or more cold cathode fluorescent lamps (CCFL) 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 CCFL. 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. The built-in burst oscillator can be synchronized with a [ ... ]
