Peltier on a voltage regulator, TO BE or NOT TO BE

The SIC471 is much cheaper at Mouser. But this chip is difficult to solder on pcb without skills or equipment.

The TPS that was posted earlier is much easier to handle even with just the tools we all have and is much much cheaper.

But as Richard also noted, there are many other ways to do it, rearranging the needs.

A lot of this is more than just "my project", I'm often taking detours to fill in that humungous gap from not having any formal electronic education. I tend to remember things more by doing, than just reading.

I don't NEED 5A yet, I just tend to over-design stuff so that I'm never pushing stuff. Right now I'm probably using 1.5A at the most (I haven't powered 3 LED strips simultaneously yet).

I also am designing the power circuit for future use. I intend to make consoles for many more planes, each more complex and power hungry (servos, relays, etc).

I'm essentially following the capacitor voltage rating rule; a rating 2-3 times higher. (3 x 1.5A = 4.5A)

And yeah, I might just power the "logic" direct off USB.

Designing for one-off its OK to do that. But for production is not efficient (economically speaking). But then again, its your money.

If you paln to add later other features, just make model 2, model 3 to cover the added specs.

Sell some basic models, get the money to make a bigger model with bells then on the third add whistles too!
