Working Principles
The UC2524DWTRG4 is a voltage-mode PWM controller that regulates and controls the output voltage of power supplies. It operates by comparing the feedback voltage with a reference voltage and adjusting the duty cycle of the PWM signal accordingly. The internal oscillator generates a sawtooth waveform, which is compared with the error amplifier output to generate the PWM signal. The duty cycle determines the average output voltage, which is then filtered and regulated to provide a stable output.
