Latest Patents

Ezra’s listed patent, “Output Conduction Detection in a Buck Converter,” describes an integrated controller designed to detect when current is conducting at a buck converter’s output. The detector gives the controller’s input, or high side, visibility into the discharge period, helping prevent continuous current mode operation when the output is short-circuited.

The controller receives a feedback signal indicating the converter’s output voltage and produces an input drive signal. A bias drive circuit uses that signal to generate a bias drive signal, which can turn on a bias transistor. The detector identifies an output conduction event by sensing a voltage drop across the bias transistor, caused by freewheeling current passing through the transistor or a bias diode. It then produces an output conduction signal.

Career Highlights

Ezra’s listed patent reflects work on power-conversion control and circuit protection. Its detection approach is intended to help a buck converter respond to output conduction conditions, including those associated with a short circuit.
