I have some simple questions about TPS65265. This is 3 output Buck Regulator.
I want to control EN1/EN2/EN3 seperatly.
From the datesheet, If i make Mode Pin(#7) floating then, Buck1/2/3 are controlled separate by EN1/2/3.
And in the datasheet, to enable these EN1/2/3, then I should make En1/2/3 pins float because there is internal pullup current source which can make EN pin with floating.
Here, I am confused.
To Control Bucks separately -> Mode Pin Float
To make En1/2/3 Enable -> En1/2/3 Pins are Float.
I want to control En1/2/3 from output logic. But If En1/2/3 pins are floating to enable automatically with internal current source, then How can I control this from outside of IC?
And, one more question.
In the datasheet page 16 there is about UVLO.
Is the Vstart means Uvlo Upper threhsold? and Vstop means UVLO Low threshold?
