Description

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...
