    Hi Jimmy,

    The TPS628304 can be used for the 5V to 3.3V rail. You should be able to get more than 93% efficiency. The max current of the TPS62830x family is 4A.

    For the 4.5A rail, you could recommend the TPS62869 or TPS62870Z0. The efficiency will be a bit less than 93%.

    Best regards,

    Varun
