Abstract
A gate driver circuit includes a first power supply rail providing a first fixed supply voltage; a second power supply rail providing a second fixed supply voltage; a transistor including a gate terminal having a gate voltage; and a gate driver integrated circuit (IC) supplied with the first fixed supply voltage and the second fixed supply voltage, the gate driver IC including an output terminal configured to provide a gate drive voltage at the output terminal in order to drive the transistor between switching states. The gate driver IC includes a first voltage converter configured to modulate an amplitude of the first fixed supply voltage to generate a first modulated supply voltage; and a first switch configured to selectively couple the first fixed supply voltage and the first modulated supply voltage to the output terminal of the gate driver IC in order to regulate the gate drive voltage.
