Claim 0:
1. An apparatus, comprising:
a regulator having a feedback input, a regulator control output, and a duty cycle output, the feedback input adapted to be coupled to a power output of a power converter;
a clock generator having a spread spectrum modulation circuit, a first delay generator, a second delay generator, a first output, and a second output, the spread spectrum modulation circuit having a modulation output, the first delay generator having an input and a first delay output, the input of the first delay generator coupled to the modulation output, and the first delay output coupled to the first output, the second delay generator having a first input, a second input, a duty cycle input, and a second delay output, the first input of the second delay generator coupled to the modulation output, the duty cycle input coupled to the duty cycle output, and the second delay output coupled to the second output;
a current control comparator having first and second comparator inputs and a comparator output, the first comparator input coupled to a current sense output of the power converter, the second comparator input coupled to the regulator control output, and the comparator output coupled to the second input of the second delay generator; and
a driver circuit having a first signal input, a second signal input, a first signal output, and a second signal output, the first signal input coupled to the first output, the second signal input coupled to the second output, the first signal output adapted to be coupled to a first switch control input of the power converter, and the second signal output adapted to be coupled to a second switch control input of the power converter.
