Abstract: In an example, a controller device for a resonant converter includes processing circuitry configured to output a first switching signal and a second switching signal. A switching module is configured to electrically couple a primary side winding of a transformer to a voltage source during an activated state of the first switching signal and to electrically couple the primary side winding to a reference node during an activated state of the second switching signal. The processing circuitry is further configured to determine a first synchronous rectification signal and a second synchronous rectification signal. A synchronous rectification module is configured to generate a first channel for a first secondary side winding of the transformer during an activated state of the first synchronous rectification signal and to generate a second channel for a second secondary side winding of the transformer during an activated state of the second synchronous rectification signal.

Abstract: In accordance with an embodiment of the present invention, a method of operating a power supply circuit includes receiving an input signal comprising a request for a target power supply voltage and/or current at an interface circuit at a secondary side of an adjustable power supply. The input signal is converted into a digital signal comprising the target power supply voltage and/or current. The digital signal is transmitted via a galvanically isolated signal path to a controller in a primary side of the adjustable power supply.

Abstract: In order to convert an input power to one or more DC power levels that are provided to an output load, some aspects of the present disclosure relate to techniques for driving a switching regulator as a function of a pulsed voltage signal. In particular, this pulsed voltage signal is provided substantially at a target frequency, but exhibits frequency jitter that causes the pulsed voltage to vary slightly from the target frequency in time. The frequency jitter has a frequency range that varies as a function of the output load.
