I have a power supply with a different connector, and output (on one of 24 pins) to the circuit input I am attempting to use it with, so basically I got an electronics engineer I know to make an adapter up for me, he did a great job in doing so however I have one issue, one of the pins of this adapter's input side is of 5V DC but I need it to be 12V DC on the output, the engineer used a simple 0-240V to 12V transformer however this doesn't appear to be working.
What is the best way to achieve this 5V DC to 12V DC conversion? Thank you in advance.
If the engineer told you to use a transformer to step up a DC voltage he is not, or at least should not be, an engineer, transformers only work with AC.
With that said the only way I am aware to get this to work from a DC supply is something called a buck boost. Without spending much time looking into it here is a link http://www.hobby-hour.com/electronics/lm2577-switching-regulator.php as far as I can tell it is accurate.
fyi I am a Electrical and Computer Engineer
