Abstract
A method for controlling a buck converter of an alternating current (AC)-powered light emitting diode (LED) circuit. The method includes receiving an input voltage, and converting the input voltage to a feedback voltage. The method can also include sending the feedback voltage to the buck converter. The feedback voltage is proportional to the input voltage by a first factor when the input voltage is less than an upper threshold voltage and greater than a lower threshold voltage. The feedback voltage is proportional to the input voltage by a second factor when the input voltage is at least as great as the upper threshold voltage. The upper threshold voltage is less than a maximum voltage of the input voltage.
