Good Morning.
We are Manufacturer of many type of products and we are using the LM2596 module that has being selling in the web in site like ebay. The idea is use it like the power supply for our products, but we are having some trouble and i want to know your opinion.
We are making probes in more o less 10 circuits with this module, but three of them failed in the test. The module are off and do not have output voltage after a few days working. The output current we are using is less that 400ma.
What could be the problem?
