Hi,
I'm new to PCB design, and I'm building a synchronous buck converter PCB using Altium Designer. My design is heavily based on an evaluation kit designed by CREE (attached below). The problem is that the gate drivers in the circuit generate +22V and -5V bias to drive SiC MOSFETs (Cool-MOS). I want to use the same gate drives to to drive a GaN-HEMT devices which require +5V and 0V bias.
Is it possible to add a voltage regulator to adjust the gate bias for the GaN-HEMT devices, or do I have to use a different gate driver? I'm doing this as a project for my dissertation and I'm running out of time and options. I would be grateful if you could provide me with a quick solution (if there is) for this problem.
Thanks
Amar
