Abstract
In one embodiment, a controller for a power supply may be configured to operate as a quasi-resonant controller while operating in a discontinuous current mode and to operate as one of a pulse width or pulse frequency modulation controller while operating in a continuous current mode. The controller may have an embodiment that varies a frequency of the switching drive signal around a center frequency while operating in the continuous current mode, and varies a value of a current sense signal but not vary the frequency of the switching drive signal around a center frequency while operating in the discontinuous current mode.
