MP1018
Flat Panel Monitor
CCFL Driver Controller
General Description
Features
The MP1018 is a Cold Cathode Florescent
Lamp (CCFL) driver controller optimized for
flat panel monitor applications. Designed to
run off 12 or 15V input supplies, the MP1018
can drive up to 30 lamps (150W) via four (4)
external N Channel MOSFETs. Its full bridge
architecture converts unregulated DC input
voltages to the nearly pure sine waves
required to ignite and operate CCF Lamps.
The MP1018 supports analog and burst
dimming without the use of external
components. It has soft on and off burst
waveform shaping, lamp current regulation,
transformer secondary current regulation,
output over voltage protection and a dual
mode fault timer.
The MP1018 is available in the 28 lead
TSSOP and SOIC packages.
