    Help me put together a parts list for a 5V Regulating circuit...

    Hey guys - I'm not an engineer so I really need help putting together a Digikey parts list for building a 5V 6A voltage regulator.

    From reading the threads here, I've decided to not go with a linear regulator and stick with the TI ISR PT6625 Module. Please help me build my Digikey parts list. I know I need some regulators and caps, so please help me finish the following (I also may ask for a rough sketch of how to put things together):

    1.) Perf board (from Radio Shack)
    2.) PT6625D-ND - $30.03

    Thanks in advance!

    -HD

    hd, that is an integrated dc-dc converter. All you need are the basic components listed on the datasheet: 330uF cap on the input and output. Here is the datasheet, since the link on the digikey page didn't work (at least not for me) http://focus.ti.com/lit/ds/symlink/pt6625.pdf.

    Just wire it up exactly as show on the 1st page, with the components indicated in the diagram. You won't need the mosfet if you don't intend to put it in standby (you can just fully turn off/disconnect main power some other way such as a relay).

    You may want to add some additional caps for better filtering, but it likely will be fine just using what the suggest.

    Basic Parts list:
    what you already stated
    2-330uF caps 16-20volt
    solder
    wire
    time
