Single Stage Buck PFC Controller for LED Lighting

The DIO8850B is a single stage Buck PFC controller targeting at LED lighting applications. It drives the Buck converter in the quasi-resonant mode to achieve higher efficiency. \n\nIt keeps the Buck converter inconstant on time operation to achieve high power factor. • Valley turn-on of the MOSFET to achieve low switching losses\n• 0.3V current sense reference voltage leads to a lower sense resistance thus a lower conduction loss\n• Low start up current: 15μA typical\n• Reliable short LED and Open LED protection\n• Power factor >0.9\n• Compact package: SOT23-6, ;
