--- Quote from: Docara on November 23, 2019, 05:04:43 pm --- Via Aliexpress I was finding I could get 30pcs of the MP1584 populated board (the same ones that JohnnyBerg has since posted here) for £0.45 + postage but had no control over anything obviously. I found a number of (albeit anecdotal) reports that these boards didn't follow the applications notes or component values causing instability). --- End quote --- The boards you get from Aliexpress usually don't even have a genuine switcher IC. For example, practically all boards with the LM2596 that are all over Aliexpress and Ebay have a different, relabeled chip that uses a different, lower switching frequency. Of course these don't meet the spec for the LM2596, but you only notice if you drive them hard. |

yeah thanks for the heads up, I was beginning to suspect something was a bit suspect. |
