About the difference in frequency between INN3168 and INN3270

Posted by: 吹田敦 on Tue, 10/19/2021

I’m considering replacing INN3168C-H107 with INN3270C-H217.

When only the ICs were replaced on the same board, the INN3270 was operating at a lower frequency than the INN3168 even under the same input / output conditions.

What is the origin of this difference?

Hi 吹田敦,

INN3270 has higher Ilim vs INN3168.


Ilim (primary current limit, as shown in the datasheet).
