Working Principles
UCC2813PW-3 operates based on the voltage mode control technique. It compares the feedback voltage (FB) with a reference voltage (VREF) to generate an error signal. This error signal is then amplified and used to adjust the duty cycle of the PWM signal. By modulating the duty cycle, the output voltage is regulated.
The peak current mode control ensures stable operation by sensing the current flowing through the power devices. This allows for effective control of the power supply's output.
