Tool/software:

Hello TI Team,

I am using three TPS62873 devices in a stacked application, consisting of one primary and two secondary devices. The datasheet specifies that the SYNC_OUT pin of the secondary device needs to be pulled down to ground with a 47K resistor.

I would like to confirm if this means that the SYNC_OUT pin of *all* secondary devices should be pulled down to ground with a 47K resistor.

Thank you for your clarification.

Best regards,

Xiangling

Hi Xiangling,

Thanks for reaching out to us.

You are correct. Terminate SYNC_OUT pin of all secondary converters to GND via 47kohm resistor. Refer to the reference schematic below.

If you like, we can communicate via email so I review your schematic diagram in details while retaining the confidentiality of your documents.

Best regards,

Excel
