TPS65631W: About how to set Neg voltage

Part Number: TPS65631W


I just want to confirm that, when configuring the Vneg, TPS65651W just counts the pulse number for one time after power on, and doesn't need receive pulse continuously during operation, correct?

Thank you

  • Hello Robin,

    Not sure if I understood your question completely. Do you mean if the converter sends a kind of 'acknowledge bit' after it counts the pulse number ? If this is the case then the answer is no, the converter passively counts the required pulse number on the CTRL-pin and sets the according voltage. As long as no additional pulses are applied on the CTRL-pin the device will not change the output voltage.

    Let me know if this answers your question.
    Best Regards.
