  • RE: TPS23751: TI solution suggestion

    Resolved
    Hey Jimmy, For the TPS23751, I would switch to the next generation part - TPS23731. The TPS23731EVM-095 is a 48V to 5V design for 25W (note it is 25W at the input). A higher power IC is needed for 30W at the output. I would suggest the TPS23730. Can…
