Working Principles
The FAN6921MLMY is a Pulse Width Modulation (PWM) controller IC used for power management applications. It regulates the output voltage by adjusting the duty cycle of the PWM signal. The feedback pin (FB) compares the actual output voltage with a reference voltage, and the compensation pin (COMP) ensures stability by adjusting the control loop response. The current sense pin (CS) monitors the output current to protect against overcurrent conditions. The enable pin (EN) allows for device on/off control, while the soft-start pin (SS) gradually ramps up the output voltage during startup. The gate driver output (DRV) provides the necessary signals to control an external MOSFET.
