Hello!
What are the differences between LT3470 and LT3470A?
I would guess:
Only different Packaging with lower Rthja for LT3470A and slightly higher biased and therefore faster error amp or also a bigger switch transistor?
The reason for my question is:
We are using both variants in a few applications and after we had to change the inductor due to obsolescence, I am trying to minimize retest efforts.
Best regards
Robert
