Working Principles

The FAN7601BM is a voltage mode PWM controller that regulates the output voltage based on the feedback received from the FB pin. It utilizes an internal oscillator to generate a pulse-width modulated signal, which controls the duty cycle of the power switch. By adjusting the duty cycle, the output voltage can be regulated within the desired range. The COMP pin allows for compensation adjustments to ensure stability and prevent oscillations. The CS pin monitors the current flowing through the power switch, providing overcurrent protection. The SS pin enables a soft-start function, gradually increasing the output voltage during power-up to avoid sudden voltage spikes.
