Abstract
Systems and methods for providing a rapid switchable high voltage power transistor driver with a constant gate-source control voltage have been disclosed. A low voltage control stage keeps the gate-source voltage constant in spite of temperature and process variations. A high voltage supply voltage can vary between about 5.5 Volts and about 40 Volts. The circuit allows a high switching frequency of e.g. 1 MHz and minimizes static power dissipation.
