description An LED controller circuit for use in an LED drive circuit in which a coil current control scheme is used to deliver power to an LED arrangement from a phase cut dimmer. The controller circuit includes means for determining, based on an analysis/signal processing of the on-time of the transistor, the dimmer characteristics, including the on state and off states of the ac dimmed voltage signal. This avoids the need for the controller circuit to process the dimmer output.
