The operation frequency of these control signals is set to 200 KHz meaning that the input voltage is pulled down to zero once in every 5 μseconds. This value is a hundred-fold of PWM generator’s operation frequency and thus is sufficient ...

... Using R1 of 4.7M and R2 of 1M, the current consumption will be about 0.5 uA (0.0005 mA) for a Vcc of 3.0 V. Higher values for R1 and R2 can be used to further limit the current, but board impedances must be considered if higher resistance is used. Experiment with C1 values for various filterin ...
