Introduction

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

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: 15μ typical
Reliable short LED and Open LED protection
Power factor > 0.9
Compact package: SOT23-6, SOIC-8
