Abstract: A controller for a power converter and method of operating the same. In one embodiment, the controller includes an inductor-inductor-capacitor (“LLC”) controller configured to receive an error signal from an error amplifier to control a switching frequency of an LLC stage of the power converter to regulate an output voltage thereof. The controller also includes a power factor correction (“PFC”) controller configured to control a bus voltage produced by a PFC stage of the power converter and provided to the LLC stage so that an average switching frequency thereof is substantially maintained at a desired switching frequency.

Abstract: A controller for use with a power converter and method of operating the same. In one embodiment, the controller includes a gate drive terminal configured to provide a gate drive signal to enable conductivity of a power switch during a first portion of a switching interval and to disable conductivity of the power switch during a second portion of the switching interval. The controller also includes a current sense terminal configured to receive a power switch signal indicative of a current in the power switch during the first portion of the switching interval, and receive a control signal to operate the power converter or provide a status signal indicative of an operating condition of the power converter during the second portion of the switching interval.

Abstract: A burst mode controller for a power converter and method of operating the same. In one embodiment, the burst mode controller includes a burst mode initiate circuit configured to initiate a burst mode of operation when a signal representing an output voltage of the power converter crosses a first burst threshold level. The burst mode controller also includes a voltage elevate circuit configured to provide a voltage elevate signal to raise the output voltage if a time window expires before the signal representing the output voltage of the power converter crosses a second burst threshold level.
