Monolithic Power Systems MP1015 Full System Precision CCFL Driver 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 Ordering Information Part Number∗ Package Temperature MP1015EM TS [ ... ]
