Hi,
my customer is using BQ25790 operating in 1.5MHz.
In datasheet, it says
Please note that the 1.5 MHz switching frequency only works with the 1µH inductor and the 750 kHz switching frequency only works with the 2.2µH inductor
Why so strict?
My customer would like to use 0.68uH inductor at 1.5MHz, it would bring larger ripple than 1uH. If they can accept the ripple, what else is wrong with 0.68uH?
