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.
Output Current Adjustment by PWM Control (Dimming):
A PWM signal must have a frequency of greater than 100Hz to prevent any visible flicker.
