Voltage supply circuit for switching transistor operated in high-side circuit has charging capacitor that supplies driver circuit operable at first potential or at least second higher potential

摘要

The circuit has a drive circuit via which supply voltages at different potentials can be provided connected to the switching transistor gate connection. A charging capacitor that supplies the driver circuit with voltage can be operated with clock phases dependent on a clock generator at a first potential or at least a second higher potential. The potential is supplied by a circuit that pumps the first potential up to the second potential.
