Topic: step-down lm2596s not working (Read 111 times) previous topic - next topic



So I bought a step-down module with LM2596S here and I have tested it and it doesn't work... I connected a 9V battery to its IN+ and IN-, and the output voltage just stays around 7.12. Also I payed attention while connecting - and +. I tested the little diode next to lm2596s with diode check(like suggested in one video on youtube) but it did display some values so the diode I think is ok. I'm not sure why it doesn't work. Can I fix it somehow or is it just dead?

Thanks in advance,
