Reducing switching losses associated with a synchronous rectification MOSFET

摘要

A synchronous rectifier is described that includes a transistor device that has a gate terminal, a source terminal, a drain terminal, and a field-plate electrode. The field-plate electrode of the transistor device includes an integrated diode. The integrated diode is configured to discharge a parasitic capacitance of the transistor device during each switching operation of the synchronous rectifier. In some examples, the integrated diode is also configured to charge the parasitic capacitance of the transistor device during each switching operation of the synchronous rectifier.
