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.
