Bleeder circuit having current sense with edge detection

A power converter for use in a lighting system, comprising:

• a driver circuit coupled having an input coupled to receive an input signal to drive a load coupled to an output of the driver circuit;
• and
• a bleeder circuit coupled between first and second terminals of the input of the driver circuit, the bleeder circuit comprising:
• a current sense circuit coupled between first and second terminals of the input of the driver circuit, the current sense circuit coupled to output a current sense signal in response to an input current through an input of the power converter coupled to the input of the driver circuit;
• an edge detection circuit coupled between the first and second terminals of the input of the driver circuit, the edge detection circuit coupled to output an edge detection signal in response to the input signal coupled to be received by the input of the driver circuit;
• and
• a variable current circuit coupled between the first and second terminals of the input of the driver circuit, the variable current circuit coupled to conduct a bleeder current between the first and second terminals of the input of the driver circuit in response to the current sense signal, the variable current circuit further coupled to conduct the bleeder current between the first and second terminals of the input of the driver circuit in response to the edge detection signal.
