TPD5S115: what is the maximum output current

Part Number: TPD5S115

Hi Sirs,

Sorry to bother you.

When we test HDMI CTS 7-11, we found if machine to load 0.02mA, the output will keep normal value 5.0288v. But if load lower than 0.01~0 mA, the output will be 6.483V. There will make 7-11 test result fail.

So, is this phenomenon is normal?

    Is there any further more info for this issue? 

    Please advise if any direction for next step, thanks for support.

    Hi Sirs,

    We have recorded a video to show that how to reproduce 5V abnormal issue, please let us know your opinion if you can also reproduce this issue on your side? 

    Thanks!

    I have searched for an EVM for this part and it is not available, even internally.

    I am attempting to get one of the original characterization boards, but have not found one yet.

    I have reviewed your results with the design team and we have no explanation for the behavior that you are seeing.

    Can you try adding a 500k Ohm resistor to the output of the boost converter so that it always sees a 1uA load and repeat your test?
