hi dear supporting,

how about the max power consumption of LMK00105 over temp? tks a lot!

    There is no information on power consumption over temperature. You could calculate the typical consumption using the datasheet values.

    I could take a bench measurement on the EVM for you if you let me know your input frequency, supply voltage, and temperature.

    Kind regards,
    Lane

    hi Lane,

    thank you for reply！ the frequency is 100kHz, and core supply 3.3V, IO supply 1.8V, need the max power consumption over whole temp range. is it possible get the data by simulation? tks!

    Hi Vera,

    For 100kHz frequency, there will not be much switching current (<1mA measured). You will basically only dissipate power in the core, and the core current is 25mA max. 30mA max is a safe estimate for 100kHz.

    Kind regards,
    Lane
