Part Number: TPS23880EVM-008
Other Parts Discussed in Thread: TPS2372-4EVM-006, BOOST-PSEMTHR-007, USB2ANY, TPS23880, MSP430FR5969

Dears,

We have got the TPS23880EVM-008,BOOST-PSEMTHR-007 and TPS2372-4EVM-006 demo,we want to verify 802.3bt POE application and want to check how large power these DEMO can be loaded.

but we can't have the USB2ANY board to connect PC.

We supply  TPS23880EVM-008 demo board's J1 with 48V, and supply 3.3V_USB with a external 3.3V,but we can't get port voltage output,How to make to get the TPS23880EVM-008 work? Does the USB2ANY must be used to connect PC to config then can work?

Thanks!

    Hi user5195153,

    If it is your first time to use your USB2ANY adapter, you will need to download the USB2ANY firmware. Did you see a window popping up and asking you to hold the RESET pin and download the firmware?

    TPS23880's default operating mode is off mode and it has to be configured through host.  The EVM has 2 options for host control: TPS23880EVM GUI through USB2ANY or MSP430FR5969 launchpad. Please refer to TPS23880EVM user's guide for more details. Thanks.

    Best regards,

    Penny
