Description
A schematic-only project to demonstrate how a bootstrap capacitor works. The overall circuit is a DC to DC Buck converter (see [Buck converter, from Wikipedia](https://en.wikipedia.org/wiki/Buck_converter)): - The control signal is a 20kHz, 50% PWM wave. - The power source is 12V DC. - The MOSFET is a N-Channel, requiring a positive voltage between gate and source of at least 5V. To simulate it, use the following configuration: - Transient - Maximum timestep: 0.1us - Stop time: 100us - Start time: 0
