UCC5350: Maximum working Frequency

Hello Don,

I would need help calculating this because I am using it to drive some SIC MOSFETs to give an output of 30 to 60 kW.

Ikenna.

Hello Don.

I used the UCC53X0 Thermal Calculator. This is what I am getting.

Do you have any other gate drive I can use to drive a parallel SIC mosfet without it getting out and giving overshoot like this one?

Ikenna.

Hi, Ikenna,

Do you have a PCB designed with our chip on it?

Best regards,

Don

Hello Don,

this is pcb design and the chip (UCC5350MCD).

Hi, Ikenna,

OK, so now it changes from a theoretical discussion to problem solving!!!

Do you also have a snip of the schematic around the IC?

Best regards,

Don

Hello Don,

I can share with you. If we can chat private not here.

Ikenna.

Hello Don,

This is the schematic around the IC.
