Abstract
A light driver includes a pulse generator circuit configured to generate a pulsed signal based on a rectified input line voltage, a dimming detection circuit configured to determine whether phase-cut dimming is present at an input of the light driver based on the pulsed signal and to generate a phase-cut detection signal, and an input selection circuit configured to apply a first voltage or a second voltage to a reference input of a power factor correction (PFC) circuit of the light driver based on the phase-cut detection signal.
