Stumped troubleshooting a Cetek battery charger here. I am pretty weak on switch mode supplies.
There were 2 terminals on the transformer that were open to any other xfmr nodes so I figured that was probably the problem.
Unwound the xfmr and actually those leads just go a couple cm in next to shield wrap layers and end...what the actual *&%#?
I pine for the days of simple pass regulated linear supplies where I understood what was going on. Can anyone explain what is going on here?
