Hi TI,

Can you please let me know what the input capacitance is for the In+ logic input for the UCC27624?

Hello Alex,

The input capacitance is not specified, but it is a very small value.

Thanks,
Annabelle

I don’t need to know the exact amount, but it would be very nice to know if it’s <= 1pF, or <=3pF, etc. Please advise

Hello Alex,

About 1pF comes from the the die. The package adds about 0.3pF, totaling 1.3pF.

Thanks,

Annabelle
