PWMIC
PWMIC stands for Pulse Width Modulation Integrated Circuit. It is a type of electronic component designed to generate a pulse width modulated signal. Pulse width modulation is a technique used to control the power delivered to an electrical device by switching the power on and off rapidly. The duration of the "on" time, relative to the total period of the signal, is called the duty cycle. By varying the duty cycle, the average voltage supplied to the load can be adjusted.
PWMICs are commonly used in a variety of applications. One prominent use is in motor control, where
The internal workings of a PWMIC typically involve generating a sawtooth or triangular waveform and comparing
