Abstract: One embodiment includes a power regulator system. The system includes a switch control stage configured to generate at least one activation signal based on a pulse-width modulation (PWM) signal and to control a respective at least one switch to generate an output voltage. The system also includes a feedback stage configured to generate the PWM signal based on a ramp signal and a feedback voltage that is based on the output voltage. The system further includes a ramp generator stage configured to adaptively generate the ramp signal based on the output voltage and based on the at least one activation signal.
