Abstract
Detecting failure modes of DC to DC power converters. In a system comprising a lighting microcontroller communicatively coupled to a direct current (DC) to DC power converter coupled to light-emitting diodes (LEDs) by way of an inductor, an example method may include: commanding, by the lighting microcontroller, the power converter to control an average current provided to the LEDs; reading, by the lighting microcontroller, values from the power converter; and detecting, by the lighting controller, one or more failure modes of the power converter based on the values.
