Abstract
This disclosure describes techniques for controlling a power supply voltage for a high-side gate driver that is used in a power converter. In some examples, in response to an overvoltage condition that occurs on an input voltage lead of a power converter, a power converter may decouple a terminal of a charge pump capacitor from the input voltage lead, and couple the terminal of the capacitor to a reference voltage lead. In further examples, in response to an overvoltage condition that occurs on an input voltage lead of a power converter, a power converter may turn off both switching transistors.
