摘要
A switch mode power supply includes an input, an output, and a power converter coupled between the input and the output. The power converter includes a transformer having a primary side and a secondary side, and a clamping circuit. The clamping circuit has a switching device coupled to the primary side of the transformer. The power supply further includes a control circuit coupled to the switching device. The control circuit includes at least one isolation component. The control circuit is configured to receive a signal from the secondary side of the transformer via the at least one isolation component, and control the switching device coupled to the primary side of the transformer in response to the signal received from the secondary side of the transformer via the at least one isolation component. Other example power supplies, power converters, control circuits, etc. are also disclosed.
