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. |
