Part Number: TPS568230

Hi Team,

Customer requested Fsw range SPEC. DS only provides TYP value. Could you kindly advise MIN and MAX value for Fsw?

TPS568230:

Thanks and best regards,

    Hi Terry,

    TPS568230 us a DCAP3 device and it does not have any internal oscillator to set switching frequency. So the switching frequency min/max is not directly specified since the switching frequency is dependency to Vin/Vout/Iout/FCCM /OOA/ECO mode. You can get an idea of its variation by looking at figure 20-28 in the datasheet.

    Hi Nancy,

    Sorry for the unclear description.

    Customer set the device at FCCM mode, Fsw 600KHz by external resistor divider(110K/51K) at mode PIN.

    They would like to know the reference Fsw distribution range for this setting.

    We know that DCAP3 devices Fsw will change due to many factors. Thus, a distribution range only for reference is OK. No need for a guarantee value. 

    Could you please advise?

    Regards,

    Terry

    Hi Terry,

    Please refer to Figure 26 in the datasheet for 600kHz range as below. We don't have distribution data available.

    Hope this helps,

    Thanks,

    Nancy
