Hi all,

I have power converter "OKY-T/10-D12" from MURATA. The converter should provides 5 volt output up to 50W. When It works without load 5 volt is ok but as soon as the current increases to more than 1 Amp the voltage drops to less than 4.9? Do you have any idea how to solve this or to use another product?

Cheers
Hadi

That says you have 0.1 ohms of resistance between
where the feedback is done, and where you measure.
That or the converter has 0.1V/A load regulation. You
could look that up and figure out whether that kind of
drop is within spec, or outside the converter.

Remote feedback is a possibility. If there is a LOADS
and GNDS pin-pair on the output terminal block.
 

Well that 0.1V drop is outside the load regulation spec for the converter. Make sure You're measuring voltage at the same point where the feedback is connected, otherwise the measurement may be off.
