Abstract:
1. A method of providing power from an alternating current (AC) power source to a light source via a driver circuit, said method comprising: receiving power at a controller of the driver circuit from the AC power source via an AC to direct current (DC) converter; initializing the controller in response to receiving power from the AC-to-DC converter; after initializing the controller, enabling power, via the controller, from the AC-to-DC converter to a peripheral circuit; after enabling power from the AC-to-DC converter to the peripheral circuit, providing a drive signal from the controller to a DC-to-DC converter of the driver circuit, wherein monitoring, via the controller, a current of the light source, a voltage of the light source, and a voltage of a low voltage output of the AC-to-DC converter; and adjusting the drive signal as a function of the monitored current of the light source, the voltage of the light source, and the voltage of the low voltage output of the AC-to-DC converter.
