DIO8850
DIO8850 is Single Stage Buck PFC Controller manufactured by DIOO MICROCIRCUITS.
Features
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 pact package: SOT23-6
Descriptions
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.
Applications
LED Lighting Down light Tube lamp & PAR lamp &Bulb lamp
