Hi first time here; definitely not the last....
I'm looking for a PWM circuit that can be controlled by an DC voltage. The 555 based ones don't seem to be well suited for this. I don't know much about other single-chip options. I'm all about analog computing and want my output voltage (0-3 volts, but this can be modified...) to directly control the speed of the motor.
To design a circuit from scratch I imagine an inverter-based oscillator plugged into some sort of inverter based pulse stretcher with voltage control? I don't know...
But ideally done with a pre-existing chip...
Any ideas?
