Hi there,

Can TPS54020 support 3.3VIN with 5V bias?

Thanks.

    Hi Jerry,

    Yes, this is supported.

    To add onto this, any sequence is ok for the TPS54020 but I would recommend having PVIN available before EN and/or VIN. This will help to ensure a smooth output ramp. If PVIN ramps up slower than the output ramp it could result in a non monotonic output ramp.

    Best Regards,
    Anthony
