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

[Demon]

if you don't want excessive heat and or high voltage AC in your box
...

Very nice unit:

But $24.95USD for a single unit is steep. Even at 100, it's still $19.43.

That SIC471 IC goes for $7.67CAD at Digikey:

Gonna look at google for a nice schematic; it might be worth getting a batch done at JLCPCB...

Those larger power suppliers for LED applications look like they could use a fan since I'd need to enclose it. That's gonna be too big and bulky.


EDIT: Have to reread Ioannis' post in another thread. I remember him sharing 2 designs.
