Abstract:
A method of controlling an LED driver can include: generating a sinusoidal half-wave signal having the same frequency and phase as an AC input voltage by utilizing a phase-locked loop; generating a sampling signal of a peak value of an inductor current in a power stage circuit of the LED driver; generating a loop compensation signal in accordance with the sinusoidal half wave signal and a signal representing an output current of the power stage circuit; and generating a switching control signal for controlling the power stage circuit in accordance with the sampling signal and the loop compensation signal.

Claim (Index 6):
A control circuit for controlling a power stage circuit of a light-emitting diode (LED) driver, the control circuit comprising:\n a) a phase-locked loop configured to generate a sinusoidal half-wave signal having the same frequency and phase as an alternating current (AC) input voltage; b) a sampling circuit configured to generate a sampling signal of a peak value of an inductor current in said power stage circuit; c) a loop compensation circuit configured to generate a loop compensation signal in accordance with said sinusoidal half wave signal and a signal representing an output current of said power stage circuit; and d) a switching control signal generating circuit configured to generate a switching control signal for controlling said power stage circuit in accordance with said sampling signal and said loop compensation signal.
