MP1015 Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – Full System Precision CCFL Driver

Monolithic Power Systems
General Description
The MP1015 is a Power 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 (patented), it greatly increases the
power conversion efficiency. The MP1015 can be
used with analog or burst mode dimming without
any additional external components. The MP1015
offers four distinct performance advantages:
1. More light for less power
2. Smallest board implementation possible
3. Low EMI emission
4. Low cost off the shelf components
