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.

Features
