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.
Ioutnom= Iout x Radj
Radj + 200K
The nominal output current is given by:
NOTE: Typical error is ±10% with resistive dimming control
If the value of Radj is between 0 to 2M
Ω, the maximum adjustment range will be 25% to 90%, (for Vin –Vout <10VDC)
The nominal output current is given by:
