Hi sir,


Currently we survey TI design PMP4489, but have some question need you help.

please help us to check BOM List C14, C28 spec, because capacitor spec different schematic.

  • 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.
