Output Current Adjustment by External DC Control Voltage:

Resistive Dimming Control

A simplified dimming control can be achieved using a variable resistor connected between VADJ and GND. Capacitor CADJ

is optional, it is installed to limit AC mains interference and high frequency noise. The recommended value of CADJ is

0.22µF.

NOTE: Typical error is ±10% with resistive dimming control
