Abstract
A power controller includes a compensation circuit and a control circuit. The compensation circuit is coupled to a power output circuit of a power converter and configured to receive a ramp signal, a voltage feedback signal and a driving feedback signal to generate a control-compensation signal. The driving feedback signal is associated with a phase node voltage at a phase node in the power output circuit. The control circuit is configured to compare the voltage feedback signal with the control-compensation signal to generate a comparison signal. The control circuit is further configured to output a pulse width modulation signal to the power output circuit according to the comparison signal and a clock signal. The pulse width modulation signal has a duty cycle. The control circuit is further configured to set the duty cycle according to the comparison signal and reset the duty cycle according to the clock signal.
