Since they will run long times I wanted to improve my previous design by a filter.
a settling time less than 0.009s
Why do you think that is good? It is way faster than you need, thermal time constants mean that anything less that about a second are going to be no improvement.
I have a version of the board which doesn't use the filter but I was told peltiers really hate beeing turned on and off all the time.
Hi I want to use one of my PWM pins with a low pass filter as an dac to drive a mosfet. my current design is for a fast pwm with a 0,82uF cap and a 4.7kOhm resistor. My question is do i need a pull down resistor ? and what value should it have? I would put it in front of the low pass filter.thanks for the Help
I was told peltiers don't like pulsed voltages
