Hi all,
Building the shcematic for the texas instruments GaN demo board and the bootstrap diode is designated as a "DNP" component. https://www.ti.com/lit/ug/snou140a/...ps%3A%2F%2Fwww.ti.com%2Ftool%2FLMG3410-HB-EVM
Why? Surely the upper gate drive needs the bootstrap capactior, or is there isoalted power supply providing the upper gate drive bias?
If it is left DNP, how would one bridge the connection across from the isolated power supply to the GaN driver? Surely just soldering some wire across would not be a good idea? Is it best that I include these in my design even if they are DNP?
