Part Number: TPS65381A-Q1

Tool/software:

Hello,

For our project we are using TPS65381A-Q1.

We do not need to use tracker which is VSOUT1.

I have attached typical application for the VSOUT1.

Since, I do not need to use tracker how should I connect this pins? Can I left them floating and/or can I remove 4u7 capacitor for VSOUT1 output?

Best regards,

Egemen

Hi Egemen,

If you want to use the regulator in non tracking mode then just connect track to gnd and adjust the feedback network as needed. If you do not need the regulator at all I believe you can connect vtrack to GND and leave vsfb1 and vsout1 floating. Hope this helps.

Best,

Michael Hernandez
