Other Parts Discussed in Thread: TPS65982, TPS65982-EVM

Hi Team

          My customer want to design power adapter . BTW  We have some issue from SPEC and EVM user gudie.

1 : EVM user guide SCH and BOM did not Match

    EX : R108 ==> 9.53k(SCH) / 3.74K(BOM)

    EX : C40 ==> 2200p(SCH) / 0.012u(BOM)

    EX : R88 / R97 /R109 ==> 47.5k(SCH) / 143k(BOM)

     Which one is right ?

2 :  Pin  definition issue for LSX_R2P and LSX_P2R issue .

3 : Coule you provide TPS65982 EVM SPI flash code to me?

   SPEC show : LSX_R2P (L4) / LSX_P2R(K4)

   EVM show : LSX_R2P (K4) / LSX_P2R(L4)

     Which one is right ?

    Kerr,

    1) The schematic is correct. The BOM is reflecting values that were used on EVM Rev. B

    The TPS65982-EVM in production is Rev. D, and the EVM schematic in the User's Guide clearly indicates Rev. D

    2) The TPS65982 SPEC (datasheet) is correct. The Altium schematic for the TPS65982 IC has a typo, which has no effect on the EVM performance because LSX_P2R is not routed to another IC.

    3) The EVM SPI flash FW is provided on the TPS65982-EVM product folder, titled TPS65982-EVM Commercial Firmware. The FW comes pre-installed on the Flash IC which is programmed and tested during the Assembly process.

    Thank you for pointing out the errors on the EVM User's Guide so that we can correct them ASAP.
