The PWM signal will be very robust to noise since it is either a 0 or a 1 instead of a small analog voltage. A class-D amplifier is a very inexpensive way to convert analog to PWM. A class-D amplifier ...

Today's PWM operates interchangeably as either purely ... 1 shows a representative block diagram. Although the advantages of a fully digital feedback path are impressive — including elimination ...

The block diagram of a linear amplifier is shown below in figure ... This signal is compared with a high frequency triangle or sawtooth waveform to create the PWM signal as seen in figure 2a below.

Charging algorithm (for implementing CC-CV profile) This is shown in block diagram ... and PWM resolution. ADC resolution defines how precisely you can measure the feedback signals.
