Again, I need your ideas and experience ;-)
I want use a peltier to cool down a ccd, controlled by a mcu with a temperature sensor.
It is rated 6A and 15.4V...
Well now I need a power supply for that thing...
I wondered if I can start with 20v then use voltage regulators to bring it down to around 15V.
Since I know no regulator that can output 6A at 15.4V, is it imaginable to "join" multiple regulators to produce 6A ?
Or is better to design a real switching power supply, maybe by pwm on a 20V source ?
(which would allow me to control the peltier which is nicer than on/off)
Knowing that efficiency doesn't matter, and as usual the simpler the better ;-)
Thanks for you time ;-)
