DIO8804

Single Stage Buck PFC Regulator for LED Lighting

Features

Descriptions

The DIO8804 consists of an integrated single



Internal 600V Power MOSFET



Valley turn-on of the MOSFET to achieve low

switching losses

stage Buck & PFC Regulator and 600V power

MOSFET, specifically designed for

a

high



Current sense reference voltage leads to a

lower sense resistance thus a lower

conduction loss

performance non-isolated converter with minimal

external components targeting at LED lighting

applications.









Low start up current: 15μA typical

Reliable short LED and Open LED protection

Power factor >0.9

The DIO8804 drives the Buck converter in the

quasi-resonant mode to achieve higher efficiency

and keeps the Buck converter inconstant on time

operation to achieve high power factor.

Compact package: SOIC-8

Applications

This chip adopts special design to achieve

reliable protection for safety requirement.



Tube lamp & PAR lamp



Down light & Bulb lamp
