Connection without VTTREF

M.Honda

Part Number: TPS51206

Tool/software:

Hi
We are currently considering TPS51206.
We are considering connecting only VTT in the circuit and will not be using VTTREF.
In that case, what should the Pin of VTTREF be connected to?

Hello,

Apologies, I didn't see that there was another version of this question. I can help you out here.

VTTREF will still need the output capacitor for regulation. VTT follows VTTREF to determine it's output voltage.

James
