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

If Vin is between 7 VDC and 36 VDC it is
recommended to use the circuit shown below

If RADJ is between 0 and 2M ohm, the maximum adjustment
range of Iout is 25% to 90% (for Vin – Vout < 20V)
