MP1011EMA
General Description
The MP1011A is a Power IC offering a
complete solution for driving one or more
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 patented control techniques, it
greatly increases the power conversion
efficiency. The MP1011A supports both analog
and burst mode dimming without any additional
external components. The MP1011A offers four
distinct performance advantages:
1. More light for less power
2. Small board implementation
3. Low EMI emission
4. Low cost off the shelf components
