Hi Guys,
I have an application where I need to build a current limiting circuit to protect a circuit board.
It is a solar application. The existing circuit board can only handle max 1.6amps input but the solar panels used are delivering up to 4 amps.
I understand the easiest option is replace the panel with a smaller one. Unfortunately its a messy situation and this is not possible to do this so looking for a simple circuit that will do this.
I have found lots of circuits with MOSFETs online but not really sure how well they work.
The input voltage ranges from 20V to 28V from the panel and that is no problem. I just need to limit the current to max 1.6A
So lets say ideally it will be 24V 1.6A
Any ideas?
Something along these lines would be ideal. http://320volt.com/en/irf4905-ile-5-amper-akim-regulatoru/
The original article on this is in german, I tried translating but its not clear if I can change components to reduce the output current.
