TPS53355: Vtrip setting, whether we can use resistors below 240kohm

Hi team,

We want to check the Vtrip setting, whether we can use resistors below 240kohm? How about Rtrip 178K? Thanks.

    Hi ,

    I'm not sure I understand the concern, but you will want to use less than 240kohm. For example, the EVM uses 147kohm, so 178kohm is absolutely fine.

    Please see page 19 of the datasheet where Vtrip = Itrip * Rtrip, so in the Rtrip=178kohm example, that will put Vtrip = 1.78V.

    Let me know if I am misunderstanding the concern or if you need more information.

    Regards,
    Kris
