TPS61027: Power save mode

Shuji Ishiwata

Part Number: TPS61027


Hi All,

I have a question about TPS61027.

What is the frequency in Power save mode?
I think it's frequency changing by conditions, what are you detecting?
Is it voltage? Or is it current?

Best Regards,
Ishiwata

    Hi Ishiwata:

    There are too many factors influence to the frequency. It's batter to do the test in the board.

    May I know what's the purpose why you ask such question?

    Hi Minqiu


    Thank you for your reply.
    The customer is switching 1kHz in Power save mode.
    There was a sound, but it was improved by disabling Power save mode.

    I heard the switching frequency in Power save mode for reference in development


    In that case, please tell me the following values.
    - What is the voltage threshold for Power save mode?
    - What is the voltage threshold at which the Power save mod is released?
    - What is the threshold of the load current for Power save mode?


    Best Regards,
    Ishiwata

    Hi Ishiwata:

    If customer can accept disable the power save, it would keep high switching frequency, and no audible noisy. 

    The threshold and voltage threshold is related too lots factors and complex to give.
