Abstract

Official abstract text for this publication.

In accordance with an embodiment, a driver circuit includes a low-side driver having a first output configured to be coupled to a control node of a first semiconductor switch, and a reference input configured to be coupled to a reference node of the first semiconductor switch. The low-side driver also includes a first capacitor coupled between an output node of the first semiconductor switch and a first node, a first diode coupled between the first node and a first power input of the driver, and a second capacitor coupled between the first power input of the low-side driver and the reference node of the first semiconductor switch.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of operating a switch driver, the method comprising: charging a supply node of the switch driver with a network coupled between an output of a switch and a supply node of the driver, wherein the switch comprises a normally-on device in series with a switch transistor, and the normally-on device conducts electricity when a voltage between a control node of the normally-on device and a reference node of the normally-on device is about zero volts.…
