Part Number: TPS65983

Dear SIr 

You can saw i would like to change the PDO4 peak current from 100% to 200%

May I know if we change this value ,the power supply capability is 30W or 15W??

Thanks

    Hi Kai,

    If you change the Peak Current from 100% to 200% you can sustain current spikes up to 1.5A without hitting Over Current Protection (OCP). However, since your max current is set to 0.75A, the PP_HVE supports up to 15W. When your system sees a current spike of 1.5A however, you will not necessarily see 30W as your voltage will drop during these events and keep power roughly the same.
    I hope this helps.

    Thank you,
    Eric
