GATE CONTROL CIRCUIT

摘要

An integrated circuit for switching a transistor is disclosed. In some embodiments, an operational amplifier is configured to drive a transistor, and slew rate control circuitry is configured to control the slew rate of the transistor source voltage during turn on. The transistor source voltage is employed as feedback to the operational amplifier to facilitate closed loop control of the transistor source voltage during switching of the transistor.
