Hello Team,

please provide the junction to board thermal resistance. This information is missing in the data sheet.

Thanks and Best Regards,

Can you use the psi JB metric? Are they trying to calculate the IC temp based on a fixed PCB temperature?

If you have other details, please post them in the thread toolkit at the top.

can we use this JB thermal resistance from fig. 9 and 10 data sheet?

Thanks,

Yes, that is the psi metric that I mentioned in my first reply.

Can you share the application specifics via email? There are usually no thermal limits/concerns with this module, as it is very efficient.
