I see its specs say it can handle up to 40V input, but im unclear if the design has to be modified much in the datasheet's schematic because it quotes 12V and im unsure if it would have to be changed if I am using different input voltages.
The inductor value seems to be confusing also, since to get the full 3A output, I could either use a 22uh or 68uh inductor, which are significantly different.
I see there is a link to a PSU designer and simulator in the datasheet, but it does not work when you enter any data.
basically, you are saying that you have to design the unit to work with the voltage being fed in, so in other words, if i wanted to change to 24v from 12v, I would have to trim the pot to get me back to 5v?
Im sure ive seen buck converters out there that you can connect to virtually any voltage between 6-35v and out comes 5v without any tweaking.
If its too difficult to design this, I may as well just leave it for 12v operation, but it would have been nice if I could have simply connected the unit to any power source and still got 5v.
Ive already ordered a lot of the 5v fixed regulators anyway, so i may as well use them up lol.
And as far as the whales go, this is a regular occurrence here in New Zeland, not sure what causes it, but that sandspit is a common grounding place.
OK, thats good to know, this is what I suspected under load, but TBH - I dont think that this will be a problem.
Im only running an arduino UNO, an LCD screen and 2 small sugarcube 5V relays, I doubt this would even use 1A, going by the current these small relays draw.
The LCD probably uses more than the arduino and relays combined.
I could heatsink it to the metal box anyway.
