A device marked as LM2596 on a module can be purchased cheaper than the genuine part from TI...

mariush:
Keep in mind that the LM2596 modules from eBay may be made with LM2576 chips (they erase the text and re-print the chips with the LM2596 text) ... the difference is lower switching frequency (around 52kHz for LM2576)
Also, the  chip may actually be a XL3000 something clone of LM25x6 chips.

Basically, be wary of those cheap modules.
