1. A power conversion integrated circuit, comprising:

  • a state circuit having an output that supplies a mode signal, wherein the state circuit includes a comparator having a first input coupled for receiving a control signal and a second input coupled for receiving a first reference signal, and a memory circuit having a first input coupled to an output of the comparator for setting an output state of the memory circuit according to a value of the control signal; and

    a control circuit coupled for receiving the mode signal that sets a mode of operation, where the control circuit is responsive to a feedback signal for providing a pulse-width modulated control signal.
