Review what they have, I've used the parts, while not low cost, they can get you buy if you are not planning to design in and use.

Warpspeed, Itsmoked,
I'll get one up and running with a linear. Then do it with PWM. I just finished a floating high voltage pulser with mosfets. So, doing it is not a problem and certainly more efficient. The noise produced has to be in the 10's of milivolt level. As you guys know, switching...
Thanks for the info everyone.
But it looks like the best way to go is, just buy a Power-One supply and modify it to accept my analog input. By doing this I will reduce my build time and save money also.
So, the old trusty LM723 regulator series is the way to go.
Hi everyone,
I'm not new to design, just looking for some opinions.
The use of anything switching is out of the question due to noise produced. Noise produced results in a reduced filament life. Noise fluctuations cause heat fluctuations and this causes short life.
Filament science is...
I wish it was that easy, but if you understand filaments and how to extend the life of them, you would quickly understand how complex it can get. Thanks for the reply, I'll check the other area.
I need to design a voltage regulator for this purpose.
I want to control the voltage across a bulb filament from 0 to 2 volts with a current capability of 3 amps. I want to use a DAC for the control.
My questions is, what is best, transistor, mosfet, and I need some ideas for the circuit...
