A power control system includes a switching power converter and a programmable power factor correction (PFC) and output voltage controller. The programmable PFC and output voltage controller generates a control signal to control power factor correction and voltage regulation of the switching power converter. In at least one embodiment, the control signal is a pulse width modulated signal. The programmability of the PFC and output voltage controller provides the programmable PFC and output voltage controller flexibility to operate in accordance with programmable parameters, to adapt to various operating environments, and to respond to various operating exigencies. In at least one embodiment, the programmable PFC and output voltage controller includes a state machine to process one or more programmable, operational parameters to determine the period and pulse width states of the control signal.
