TPS65094: TPS650940A0PG1.0 software

Steven He92

Part Number: TPS65094

Dear Sir,

Does have TPS650940A0PG1.0 software(xxxx.json) could be share...

My customer load TPS650941-1.1.json to set-up TPS650940A0PG1.0 voltage, "BUCK2CTRL " can 't output correct voltage(register is set 0.51V, but output voltage is 2.1V)

Buck1 voltage setting & reading is correct.

This is load software not correct ? or another suggestion for Buck2 voltage setting issue?

Please you kindly provide suggestion.

Thanks!

Steven,

Can you ensure that your customer has the latest version of the .json file? My version looks like it is version 1.4. You should be able to download it from the link in the EVM user's guide.

Dear Nick,
I check my software file is " TPS650941-1.1.json ".
I can't find new version_1.4 on web-side, could you share new version file to me?
Thanks!
Steven

Steven,

I am not sure what changed on the 1.4 version so I would rather we just both use the version that is on the web. I am getting access to the 1.1 version now so I can test this on my end. In the meantime can you check the switch pin of BUCK2? If you set BUCK2 to 0V does it still output 2.1V? I want to see if the BUCK is regulating to this voltage, or if something else is pulling it up.

I would also make sure to write to the BUCK2CTRL register and then read it back, so you know your program is sticking.

Steven,

Have you gotten a chance to check the switch node?
