LT8390, LT8390A

Category: Datasheet/Specs
Product Number: LT8390

Hello!

I am making a Buck-Boost Voltage Regulator using LT8390 or LT8390A.

Comparing the typical applications listed in the datasheet of the LT8390 and LT8390A, in the case of the LT8390A, BST1 and BST2 are connected to INTVCC through a diode.

I'd like to know why I should use a diode and what the problems would be if I didn't.

Kind regards
