TPS63070: Internal voltage divider of TPS630701, again

Hi  Alex,

i think there will be no concern with a resister external to adjust the output voltage.

but i do not have the value of resister innernal. please wait for my update. if you have EVM on hand, could you try with bench?

Hello Tao,

Thank you for your answer. I don't have an EVM but I'll try to modify my current board. I hope to see your update!

Best regards,

Alex.

Hi  Alex,

ok, please wait for my update.

you can ask a EVM from https://tisamples.ti.com for free, if you think it is helpful

Hello Tao,

Any luck with your investigation?

Best regards,

Hi   Alex,

sorry, i totoally forgot your question.

the resister divider internal should be around 0.24meg/1.26meg.

Hello Tao,

I added 115k from Vout to FB to get a 5.5V output. This gives me about 965k for the top resistor and something like 184k for the bottom. Is it possible? Do all batches have the same values or can they differ? We usually use the TPS63070, but due to a shortage of chips, we decided to try the TPS630701.

With best regards,

Alex.
