Now that we have known the application field of SUCW61215C-C, we should know the working principle of SUCW61215C-C. The working principle of this kind of DC-DC converter is that the input voltage is adjusted by the PWM control signal, that is, the input voltage is changed according to the duty cycle of the PWM signal to adjust the whole circuit efficiency, so as to maintain the output voltage under different loads.

The specific steps of the working principle are as follows: Firstly, the rectangular wave oscillator produces a rectangular wave signal with 50% duty cycle, and this signal is transferred to the base of the NPN transistor. Then the transistor is turned on and off, and the current flows through the inductor to produce a voltage gain. Finally, the output voltage is controlled by the feedback circuit according to the output voltage and the desired voltage, and the output voltage is stable and reliable.

In summary, SUCW61215C-C is a non-isolated DC-DC converter which mainly used in telecommunication, computers and consumer electronics, and automobile industry. Its working principle includes rectangular wave oscillator, a power converter, and a feedback converter, which enables it to provide stable output voltage under different loads.
