A power converter control circuit includes a feedback circuit and a pulse width modulation signal generating circuit for configuring a power stage circuit to provide power to a load. The feedback circuit generates a first gain signal and a second gain signal according to an output voltage sensing signal coupled with the load. The feedback circuit further generates a feedback signal according to the first gain signal and the second gain signal. The pulse width modulation signal generating circuit configures the operation of the power stage circuit according to the feedback signal and a reference signal. Moreover, the feedback circuit and the pulse width modulation signal generating circuit are configured on the same integrated circuit package.
