Cheap step up converter?

Latch over 13 years ago

I need to step up 12V to 24V.

IN: 12V @ 5A OUT: 24V @2.5A

I know this is simple sounding, but I am just looking for the cheapest way to do it. Switch or linear converter is ok.

You can use the WEBENCH tool to change the values according to what you need.
You can request samples directly from TI or NS website.
