Other Parts Discussed in Thread: TPS65910EVM
Hello,
 
Could you please let me know the PSKIP threshold output current each of  VIO,VDD1,VDD2 ?
If there is hysterisis between "change from PFM to PWM" and "change from PWM to PFM", please let me know.
 
Best Regards,

    Hello,
     
    I measured threshold current of PSKIP  mode by TPS65910EVM.
    Then,  there is no hysterisis and threshold currents are the following.
     
    VDD1:about 70mA
    VDD2:about 100mA
    VIO: about 110mA
     
    Is my measurement result correct ?
    If there are any difference between specification please let me know.
    And please let me know the calculation for threshold current of PSKIP mode.

    your meaurements are close , it is around 100mA when PSKIP to PWM transition happens.

    Hello Puneet san,

    Thank you for the reply.
    Is PWM to PSKIP threshold current  same with PSKIP to PWM ?
    I think that there is no hysteresis.
