Abstract

An adjustable auxiliary power supply for a light emitting diode (LED) driver for adjusting an auxiliary power output includes a voltage regulator configured to receive a regulator input voltage and to output an auxiliary power supply voltage selected from a first output voltage and a second output voltage according to a voltage selection signal used to control an LED lighting setting. The adjustable auxiliary power supply includes a first and second input voltage circuits configured to selectively output respective first and second input voltages to the voltage regulator. The adjustable auxiliary power supply includes an adjustable resistance circuit coupled to the voltage regulator. The adjustable resistance circuit controls the auxiliary power supply voltage based upon an adjustable resistance setting of the adjustable resistance circuit. The adjustable resistance setting is configured to correspond to at least one of the first output voltage and the second output voltage.
