Working Principles

The FAN7602BM is a PWM controller designed for switching power supplies. It operates by regulating the duty cycle of the PWM signal to control the output voltage. The feedback input (FB) compares the actual output voltage with a reference voltage, and the error amplifier adjusts the duty cycle accordingly. The compensation pin (COMP) allows for stability optimization by connecting external components. The CS pin senses the current flowing through the power MOSFET, enabling over-current protection. The DRAIN and SOURCE pins are connected to the power MOSFET for switching operation.
