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. Driving the VADJ from a Microcontroller The VADJ can be driven from an open drain output of a microcontroller as shown below. The diode and resistor serve to suppress any possible high amplitude negative voltage spikes to the VADJ input resulting from the drain to source capacitance of the FET. Any negative voltage spikes will cause errors in output current and/or unstable driver operation.

To optimize the LED brightness control at high temperatures, the LEDs must have a sufficient thermal extraction path, if not the reduction in drive current will not be optimal. The thermal control threshold points are set by adjusting R2. Three values (33K, 22K, and 10K) were tested. These values were chosen to provide thermal break points of approximately 25ºC, 40ºC, and 60ºC. Note, that the LED drive current will not continually dim to zero – the thermal controls applying DC control to that VADJ pin has a dimming ratio from maximum current of approximately 5:1. Once the reduced DC level drops below the shutdown threshold of around 200mV, the LED drive current will fall to zero and the LEDs will be off. The slope of the current reduction is determined by the beta value of the thermistor. The larger the Beta value the sharper will be the resultant current control response. The slope of the current reduction is also affected by Q1’s base emitter voltage variation with temperature.
