Abstract
A bleeder controller for controlling a magnitude of a variable current conducted by bleeder circuitry between input terminals of a device is disclosed. The magnitude of the variable current is controllable in response to a control signal. The bleeder controller includes a dimming detector to classify a half line cycle as leading-edge-dimmed or a trailing-edge-dimmed in response to at least one of an input current sense signal and an input voltage sense signal.
