STMicroelectronics EVL012LED 200W LED Driver using the STNRG012

STMicroelectronics EVL012LED 200W LED Driver using the STNRG012 is an LED driver board based on a two-stage approach. It has a front-end PFC pre-regulator and a downstream resonant half-bridge converter. The EVL012LED uses the STNRG012 IC that embeds the controllers of both sections in the same device. The STNRG012 features high efficiency, low power consumption at no load without an auxiliary supply, good power factor with low harmonic content, and reduced part count.
