Claim 14:
15. The light driver of claim 14, wherein the switching circuit comprises:
a first switch configured to activate in response to the phase-cut detection signal being at a first level to apply the first voltage to the reference input of the PFC circuit, and to deactivate in response to the phase-cut detection signal being at a second level to decouple the reference input of the PFC circuit from the second voltage divider; and
a second switch configured to deactivate in response to the phase-cut detection signal being at the first level to decouple the reference input of the PFC circuit from the third voltage divider, and to activate in response to the phase-cut detection signal being at the second level to apply the second voltage to the reference input of the PFC circuit.
