PWM waveforms are commonly used to control the speed of DC motors. The mark/space ratio of the digital wave-form can be defined either by using an adjustable analogue voltage level (in the case of a ...
The circuit in Figure 1 shows a PWM (pulse-width-modulated) ramp generator that you can use in low-cost switch-mode dc/dc power supplies. Its supply voltage can range from 5 to 35V dc, and you can set ...
