Working Principles
The FAN3183MX is a high-efficiency synchronous buck regulator that converts an input voltage into a regulated output voltage. It utilizes a switching mechanism to efficiently step down the input voltage and deliver power to the load. The regulator operates by controlling the duty cycle of the internal switches to maintain the desired output voltage. Feedback from the FB pin is used to adjust the duty cycle and regulate the output voltage. The EN pin allows for easy on/off control of the regulator.
