Switching stage of a switched mode power supply, smps, as well as an smps and corresponding method

Abstract

A switching stage of a Switched Mode Power Supply (SMPS), the switching stage including a switching element including a GaN transistor connected in series with a Metal-Oxide-Semiconductor (MOS) Field Effect Transistor (FET), thereby defining a mid-node in between the GaN transistor and the MOSFET, a controller arranged for driving a gate terminal of the MOSFET based on an Pulse Width Modulation (PWM) input signal, and the controller includes first switch circuitry arranged for providing a low ohmic path between the mid-node and the gate terminal of the MOSFET and control circuitry arranged for controlling the switch circuitry based on the PWM input signal.
