11. A method of manufacturing a flyback voltage converter comprising:
coupling an inductive winding in series with a main switch via a common node;
coupling a snubber circuit in parallel with the inductive winding, the snubber circuit comprising a controllable switch having a gate coupled with a source to prevent the controllable switch from turning on; 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 inductive winding to an output voltage distinct from the input voltage.
