Hi Young,

I have another question, how do I know this current limit value since I cannot find it in datasheet!!

If customer needs higher current limit solution, how can I suggest to him?

Thanks.

Hi Peter,

Sometimes this value will not be descripted in EC table for some old parts , while you can get it by EVM board or check with AE.

May I know how much OC value do you expect ? and what's your application , VIN ,VOUT,Iout ?

Best Regards,

Young
