Series AMLD-Z Up to 1000mA | LED Driver 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.

Series AMLD-Z Up to 1000mA | LED Driver Driving VADJ Via Open Collector Transistor The VADJ can also be driven via an open collector transistor as shown below. The diode and resistor serve to suppress any possible high amplitude negative voltage spikes to the VADJ input resulting from the collector to emitter capacitance of the transistor. Any negative voltage spikes will cause errors in output current and/or unstable driver operation.
