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.

FEATURES • Controls Four External, Low Cost, N-Channel MOSFETs
• Fixed Operating Frequency
• Input Voltage Range of 10V to 32V
