Would anyone suggest a circuit for a PWM around a 556 timer that:
- near full range duty cycle (~0% - ~100%) can be controlled by a varying 0v-5v signal
- a way to adjust/calibrate input voltage vs. duty cycle (i.e. 1v = 20% duty or adjust it to 1v = 35% duty)
- ~20Hz
- the output would be using the 'on/high' part of the wave to ground a 12v to actuate a solenoid (factory boost controller for car).
Thanks,
Rey
