Hello Team,

is it possible to get a little higher Vout like 3.5V instead of 3.3V with the TPS62177 by connecting an R-divider from Vout to the Vos-pin?

Thanks and Best Regards,

Hans

    As just discussed on the phone, I do not recommend to do that. I would expect problems with output voltage regulation accuracy and depending on the difference of the output voltage to the set fixed output voltage there is some risk to run into problems with control loop stability.
    I recommend to use the TPS62175, which is the adjustable version in this family.
