Kuo,

Let me go back and check this with the original designer of this reference design and I will confirm the correct value, and request that the error get corrected.

I would expect that the sch values of 470 uF are correct, I don't think that 2 x 47-uF caps would be sufficient at this power level.

Thansk,
Bernard

The designer has confirmed my expectation that the output caps should be 2 x 470 uF, and the BOM has an error. The error will be corrected and a new BOM doc will be posted to the web-page as soon as it is available.
