HVLED101 High Power Factor Flyback Controllers

STMicroelectronics HVLED101 High Power Factor Flyback Controllers have enhanced peak current mode controllers. The STMicroelectronics HVLED101 can control mainly high power factor (HPF) flyback or buck-boost topologies having an output power of up to 180W. Some other topologies, like a buck, boost, and SEPIC, could also be implemented. Primary Side Regulation of output voltage and Optocoupler control can be applied independently on the chip, exploiting precise regulation and very low standby power during no-load conditions.
