Abstract

See full text

A circuit for driving a power switch is presented. The circuit includes a first power switch coupled to a second power switch via a switching node and a driver coupled to the first power switch, where the driver contains an energy storing element coupled to the switching node. The circuit also contains a sensor to sense an electrical parameter of the driver and a charger coupled to the sensor. The charger provides a charge current to charge the energy storage element, and to control the charge current based on the electrical parameter. In particular, a circuit for driving a power switch based on a III/V semiconductor is presented. In addition, a method of powering a power switch driver is presented. The method includes sensing an electrical parameter of the driver and adjusting a current to charge the energy storing element based on the electrical parameter.
