Claim 15:
16. The method of claim 15, wherein, if the resistor discharge voltage is less than to the reference voltage, the method further comprises:
controlling the power supply to output a second charge voltage to the light string driver, the second charge voltage greater than the first charge voltage;
storing a second capacitor voltage in the storage capacitor based on the second charge voltage;
controlling the switch into the conduction state to discharge at least a portion of the second capacitor voltage stored in the storage capacitor through the discharge path;
comparing the reference voltage with the resistor discharge voltage generated across the sense resistor in response to the discharge of the at least a portion of the second capacitor voltage; and
if the resistor discharge voltage is greater than or equal to the reference voltage, storing the second charge voltage in the lookup table.
