描述 Description

DF6811T is a high current precision Linear LED

Driver ， integrated with High Voltage

regulation switchers and JFET supply, specially

designed for AC line LED strings forwarded with

high voltage and low current.

In application, it supports a quite small BOM

benefit from no ECAP and no Magnetics, compile

with EMI and safety standard.

DF6811T can drive precision constant current by

option of an external resistor, and set up the

LED strings in group linear compile with THD

performance. Typical 40mA LED current is optimized

for 220V line voltage.
