10. A method of manufacturing a voltage converter comprising:
coupling a transformer comprising a primary winding coupled with a voltage input;
coupling a main switch with the primary winding at a node;
coupling a snubber circuit with the voltage input and with the node, the snubber circuit comprising a controllable switch having a gate and a source; and
coupling a control circuit coupled with the main switch and configuring the voltage input to turn the main switch on and off to convert an input voltage supplied to the voltage input to an output voltage distinct from the input voltage;
wherein the gate is coupled with the source to prevent the controllable switch from turning on; and
wherein the voltage converter is a flyback voltage converter.
