WebAsynchronous Buck Converter Synchronous Synchronous switching with the use of another transistor can have lower losses, but requires some rise in complexity to drive the lower gate. Most discrete solutions can accomplish synchronous switching without adding additional components to the board, so it is usually the practical switching method. Losses WebOkay. Here, I have opened LTspice and opened the buck converter schematic. We have here, this is the buck converter power stage with the input voltage Vg of 24 volts, and output voltage that supplies a five ohm load resistor. Here is the LC filter. The switch in the buck converter is realized with this power mosfet and power diode.
