s The DIO8850 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.

It keeps the Buck converter inconstant on time operation to achieve high power factor.

DIO8850 Single Stage Buck PFC Controller for LED Lighting Rev 1.

Valley turn-on of the MOSFET to achieve low switching losses 0.3V current sense reference voltage leads to a lower sense resistance thus a lower conduction loss Low start up current: 15µA typical Reliable short LED and Open LED protection Power factor >0.9 Compact package: SOT23-6.
