Hi Jimmy,

It looks ok, except for the value of C82 (the Cff). Normally, that one should be 120pF, but it shows as 2200pF in their schematic. Why do they make it so big?

Thanks,

Chris

Hi Chris,

Thanks for your great support.

We have change to 120pF.

We have another questions, could I change Cin Cap to 4.7uF?

Because Datasheet shows the Cin cap is 4.7uF. Thanks a lot.

Many Thanks,

Jimmy
