Abstract
A bleeder circuit includes an input current sense circuit, coupled to one of first and second input terminals of a driver circuit, to output a bleeder on/off signal in response to an input current through the first and second input terminals of the driver circuit. A variable current circuit is coupled between the first and second input terminals of the driver circuit and coupled to the input current sense circuit. The variable current circuit is coupled to conduct a bleeder current between the first and second input terminals in response to the bleeder on/off signal. A current scaling circuit is coupled to the variable current circuit to output a current scale signal which is received by the variable current circuit in response to a shutdown signal. The shutdown signal is representative of a conduction angle.
