Adjustable voltage regulator with "step up" capabilities

Post by mezhan » Fri Dec 18, 2015 10:40 am

Hello everyone,

New user to the forum. I have a project I am working on where I would like to use a PWM or analog output to control a 12V computer fan speed. I would like to use an RPi or Arduino board as my controller, so unfortunately I am limited to 3.3V or 5V outputs. My question is if there an IC available that will take an input voltage between 0-3.3V and output a scaled voltage between 0-12V (I suspect a 12V input would also be required)?

I see products on the Sparkfun site that allow regulation of voltage and also step up voltage ICs, but I can't find one that accomplished both.

Any help would be appreciated, thanks!
