2.5 PWM Duty Cycle Versus Output Voltage

Table 2-4 lists out the duty cycle of the PWM signal for various output voltages. A limitation on the accuracy of this measurement, is the quality of the PWM signal emitted from the function generator. Therefore, these measurements can vary depending on the PWM applied.
