Hi,

My customer would like to know the maximum and minimum switch frequency spec, could you please advise its specification?

Thanks and Best regards,

    Hello Tiger,

    The spec for the fsw min and max values is not listed. Typically we only characterize this for fixed frequency devices. Since this is D-CAP3, we do not characterize this. The frequency will vary around the 500kHz range, I attached some frequency data below for reference.

    Hope this helps. If this helped solve your issue, please don't forget to click "This resolved my issue".

    Thank you,

    Thanks Calan.

    If fact, it is better to provide the spec tolerance in number.

    We cannot judge the spec value from the figure.

    Best regards,

    Tiger

    Hello Tiger,

    Typically we do not characterize this for this device with D-CAP3 control mode. We mainly characterize these for fixed frequency devices, so I do not think we have this data for this device. A rule of thumb is about +/- 10% for frequency, so about 450kHz to 550kHz.

    Thanks!
