Abstract: A circuit includes a controller. The controller includes: a first control circuit; a second control circuit; a detection circuit; mode control logic; and driver circuitry. A first input of the mode control logic is coupled to an output of the first control circuit. A second input of the mode control logic coupled to an output of the second control circuit. A third input of the mode control logic is coupled to an output of the detection circuit. A first input of the driver circuitry is coupled to a first output of the mode control logic. A second input of the driver circuitry is coupled to a second output of the mode control logic.

Abstract: A circuit includes a plurality of control logic circuits, each of the control logic circuits configured to provide respective pulses at different time periods. The circuit further includes a timer circuit configured to provide a timer signal to each of the control logic circuits based on an output voltage, wherein the timer signal determines a frequency of the respective pulses. Furthermore, the circuit includes a rotator circuit configured to provide a plurality of rotator signals to the control logic circuits, respectively, wherein each control logic circuit is configured to determine a time period of the different time periods during which to generate the respective pulses based on the respective rotator signal.
