DIO8850BCST6中文资料Single Stage Buck PFC Controller for LED Lighting数据手册DIOO规格书

描述 Description

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.

特性 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
• Compact package: SOT23-6, SOIC-8

应用 Application

·LED Lighting
·Down light
·Tube lamp & PAR lamp &Bulb lamp
