HVLED101 Overview
The HVLED101 is an enhanced peak current mode controller able to control mainly high power factor (HPF) flyback or buck-boost topologies having an output power up to 180 W. Some other topologies, like buck, boost and SEPIC could also be implemented. Primary Side Regulation of output voltage and Optocoupler control can be applied independently on the chip both exploiting precise regulation and very low standby power...
