Hi,

I got few LM2596T-5.0 ICs and I need to know that they are working properly,
because every time I tried setting it up on bread board the output is somethig closer to 12V (my input source is a 12V 2A DC power adapter) instead of 5V.

I got 5 of them each giving the same result despite the fact they are marked "LM2596T-5.0" which supposed to give an output of 5V.

I also doubt that whether the problem is with the chip itself.

Your held will be a great help

Thanks !

Without looking at the original schematic, work backwards to trace out the connections on your test board and draw a new schematic based only on the test board. Now compare the original to the "as wired". I'll bet you find a screw-up (techical term).
