Hello there,
I have 2 DC converters (model nr in the topic name) that dont work and they both act the same way. The iductor make a really uncomfortable sound and the output voltage keeps dropping (it looks like a capacitor would be charged). I replaced some caps but that havent solved the issue.
Here i attach a video that shows exacly whats happening. I would aprichiate any tips in repairing those DC adapters!
PS: You have to turn up the volume because the inductor sound is not very well heard.
I guess you are operating the power supply outside specified range. Did you notice the minimal output current specification in the datasheet? Did you try with higher load current?

I didnt because what would be the use of a DC converter if it could not run without load?
Without any load at all it does act the same as on the video :/
