Working Principles

The FAN7710VLN operates on the principle of voltage mode pulse-width modulation (PWM). It compares the feedback voltage from the output with a reference voltage and adjusts the duty cycle of the PWM signal accordingly. By controlling the duty cycle, the IC regulates the output voltage to maintain it within the desired range. The soft-start function gradually increases the duty cycle during startup to prevent excessive inrush current.
