WebNov 4, 2024 · The key to making a shunt voltage regulator work properly is to select the appropriate diode and transistor. The saturation current in the Zener diode shown above will turn on the NPN transistor, which then allows some current to flow into the collector. Buck convertors typically operate with a switching frequency range from 100 kHz to a few MHz. A higher switching frequency allows for use of smaller inductors and capacitors, but also increases lost efficiency to more frequent transistor switching.
