Product overview
Description
This demonstration board represents a 20 W dimmable CFL (compact fluorescent lamp) ballast solution which can completely replace incandescent lamps in dimming systems. The controlled dimming range is from below 20% up to 100% of full light output without changing the triac dimmer.
Compared to formal CFL designs, this dimmable solution provides not only energy savings, but also higher reliability and significantly longer operating life.
The solution is based on the high performance ballast driver L6574, two STD4NK50Z power MOSFETs, a Zener-protected SuperMESH power MOSFET and two STTH1L06 Turbo 2 ultrafast high voltage rectifiers.
