Diode Test – Badcaps Forums

This manual also for: Find More Posts by PlainBill. Is there a cost? Diode Test I cracked open the AC adapter first thing I did, it’s very simple with only a transformer, a cap, one resistor and 4 diodes to form DC current I checked the capacitor and it was ok, both ESR and capacitance Thanks for sharing it I really like it this kind of information Thanks for your information. Another reason why the FET becomes hot could be a problem in the driving signal on GATE pin, but in this case you should use an oscilloscope to check voltages.

Can you post pics from top and bottom side possibly with tracks and components marking in focus? I also tested the D-Link switch with another known good adapter and behaviour was the same Unfortunantey I think I may have killed it now with my testing, before as I said without the diode or FET it would actually power up and blink it’s lights It did a real diagnostics test, first power turned on then it blinked each port’s light to let you know it was working Per Hansson you can calculate the output voltage if you can identify the resistors connected between output-PIN5-ground.

Without load I had the output voltage but as soon as I connected the load a resistor the IC has died My board is different from your circuit, it has a monolithic IC, so I don’t know if the behavior it is the same. I assume the DMM is just trying to inject a small amount of current through the junction of the device, and simply measures the voltage dropped over the junction based on the current.

It becomes like hotter than my soldering iron without the diode lol Anyway, so I measured the 1N diode while it was lifted, of course since it seems to be the problem I would change it but I don’t have a spare Diode Test Google for the 1N datasheet, on the second page, look at the “forward voltage characteristics”. Proceeding in this way you can understand if the problem is on the board or on the step-down converter.

Como, Italy My Country: Another thing I would do is to feed the in58222 with an external PS, if you have calculated the voltage you can feed the circuit and check if it works. So again if the only voltage feeding the board is generated by the step-down converter, removing the FET is like opening the input voltage so nothing should be powered up.
