Hi Team,
A cusotmer purchased a DC/DC step down TPS536C7EVM.
He is currently checking the output status,
there is output of Vout A but there is no output of vout B.
We do not have EVM to fix this issue,
Could you please help them how to fix no output of the Vout B ?
Please find his EVM JP setting and output monitoring for more details in the attachment.
Thank you for your assistance.

Hi Frank,
It looks like rail 2 is disabled. If you open the device config in Fusion, you should be able to add two phases to the B rail.
After setting TPS536C7 in Fusion to a 10+2 config, pressing "write to hardware", & resetting the device power, you should see the second rail become available in Fusion.
Once your rail 2 settings are written to hardware & NVM, the second rail should regulate after a restart.
Thanks,
Travis
Hi Travis,
Output B is Okay now, Thank you for your assistance.
I still don't understand the settings of TPS536C7. Can you help me?
Observing The multi-stage corresponding waveform of Vout_A.
In the process of changing phase settings in Phase Configuration,
PWM only comes out from TP31.
The place where this state wants to be the 12 Phase is not that.
Send the oscilloscope picture of the current output state.
Yellow：VOUT_ A Green:PWM1 Red:PWM2
Is the status of the phase configuration an attachment, and is there any incorrect？
Please tell me the best setting and handling method for setting the number of phase.
Thanks a lot.

Frank
Hi Frank,
Phase config should look like this to put two phases on channel B.
Thanks,
Travis
