Absolute maximum voltage of Boost-SW of LTC3633A-2

Category: Hardware
Product Number: LTC3633A-2

Hi,

Is it correct that is absolute maximum voltage of Boost-SW voltage.
I confirmed INTVcc voltage that is between 3.1V to 3.5V on datasheet. I also confirmed nearly 3.6V at Boost-SW voltage on board .
It may think that reason of capacitor between Boost-SW.
Therefore, I concern that exceed the absolute maximum voltage.

Best Regards

Hello,

Since the boost-sw pin is internally referenced to INTVCC, I think this should be fine as the controller regulates it internally.
