LM2596 help
malagas_on_fire:
Another aspect if looking also in the onsemi datasheet are the capacitors and its recomended ratings... Higher esr capacitors for cheapness could also cause troubles

This is remarked XL2579 which works at 52 kHz :)

I didn't seen these with real LM2596. Which one you're talking about? Could you give me the link on product page?

Well, I'm sure I have checked and had real ones in the past and posted a photo of a scope trace here once some years ago but I can't find that post maybe I'm imagining it.
I just checked a random sample from my current lot and indeed ~50kHz. I can't say I make a habit of checking these, so, who knows how long I've been getting 50kHz ones.
Trouble of course with any Chinese supply, you never know if you're always going to get the same as you got before.
