Hey guys,
I was wondering if anyone had a good and inexpensive PWM driver they could recommend. I'm driving a TEC at >2A, and my supply voltage is 9V (TEC voltage is between 1 and 2 volts max). I was looking at the DRV series from TI/Burr-Brown (DRV102, because Vs min is less than 9 and it's TO-220), but they were running around 8 bucks a pop. I'm not asking anyone to do my research for me, but I figured someone already had a part in mind that they've worked with that fit my needs.
Basically, I'm taking a voltage reading from the thermistor, sending it through a conditioning stage(yet to be designed), and using the output to control the PWM driver. I only need the TEC to cool, because it's attached to a laser that provides a good amount of heat itself.
Thanks guys
