What is the typical operating life of a DC DC converter? Are there any particular types that last longer?
The particulars of the DC DC converter that I might desire are: ~20-200 W, ~24-48 V input, ~14 V output. I'm just mentioning that in case high power converters tend to have a lower life.
The potential application here is to use an ultracapacitor bank to power a light. The output voltage of the ultracapacitor bank would vary with its state of charge, so a DC DC converter would be needed to maintain a constant voltage into the light source.
The idea is that both the light and the ultracapacitors could last for 10 years or more, but I am not sure if DC DC converters typically last this long (especially when in use for 12-24 h a day)...
Does anyone know? Or has anyone operated a DC DC converter for so long that they can confidently say that they do not have life issues?
I know quite a bit about ultracapacitors, but very very little about electronics.
