Abstract
Disclosed embodiments of a power converter include a power output stage for generating a first voltage output and an auxiliary power output stage for generating a second voltage output. The power converter further includes a pulse frequency modulation (PFM) controller for controlling the power output stage in response to the first voltage output generated by the power output stage during a first period of time in which the power output stage operates in a PFM mode, and a pulse width modulation (PWM) controller for controlling the auxiliary power output stage in response to the second voltage output generated by the auxiliary power output stage during a second period of time. At least a portion of the first period of time is concurrent with the second period of time.
