i understand their arguement but, i still want to give PWM a try. i'd use a frequency of 60Hz and see how it goes.
my issue is about the tc4422 being supplied 12V,4A ->> as in, if the 4A is too much.
given that i won't be running the peltier very high, i still think it should be fine at this frequency ( a heatsink provided of course).

 

I want to draw an application circuit schematic having the MSP430F6636 as it's microcontroller,would intend do simulation and capture the whole circuit diagram and print it out. I wanted to ask, is the schematic spice model of this MSP430 published ?? Cause i haven't found any so far checking online.
