Need Pin-For-Pin Replacement for PTH08080WAH With Minimum 22.2V Support

Other Parts Discussed in Thread: PTH08080W

I need to upgrade an existing device that uses a PTH08080WAH. I need to increase the max voltage from 18v to 22.2v. Does TI have a module that matches up pin-for-pin but has a higher max voltage? Thanks!

    David :

    There is no pin-pin compatible replacement for PTH08080W with  input voltage greater than  18V maximum limit.

    One  suggested is to add a pre-regulator on the  input voltage bus, Linear regulator, for conversation from 22V to 18V.

    If the output voltage for the PTH08080W is 2.5V or more, then a PTN78060WAH(3Amp), not footprint compatible could be used in place of PTH08080WAH.

    Any questions, my e-mail is tguerin@ti.com
