The ultrasonic accessory circuit board of the circuit board is controlled by a microcontroller to overcome the inherent defects of analog circuits. Through digital control methods, high-precision and high stability control characteristics are obtained, which can achieve flexible and diverse control functions. However, the working frequency and control accuracy of microcontrollers are a contradiction, and the processing speed is also difficult to meet the requirements of high-frequency circuits. This makes people seek the help of more powerful chips, so UC3875 emerged.
