Working principle

The SIT9120AI-1DF-33E133.330000X is a circuit module based on the UC2580 chip, with an operating voltage of 36V, a frequency of 33.3 MHz and a waveform output of 0.5V. The main function of this oscillator is to convert the steady electric energy into AC signal. In the processes, the energy stored in the capacitors is periodically discharged through the transistors, thus outputting the AC voltage.

The start-up and operation of this oscillator are based on the UC2580 chip. The chip provides a bias to the transistors, so that the transistors are always in the cutoff state. When the input voltage is greater than a certain threshold, the transistors can turn on and off at a certain frequency. The voltage output of this oscillator is proportional to the input voltage and the frequency of the AC voltage is the frequency of the transistor switch.
