The FSDM311 is an integrated PWM controller and MOSFET designed for off-line switch mode power supplies. It typically comes in a DIP or through-hole package with 4 pins. Here's a concise explanation of its pin configuration and functions:
1. VCC (Pin 1): This pin supplies power to the internal control circuit. It is connected to an external capacitor and resistor to maintain the operating voltage and provide startup power.
2. GND (Pin 2): This is the ground reference pin for the device. It connects the internal circuits to the ground of the power supply.
3. DRAIN (Pin 3): This pin is connected to the internal high-voltage MOSFET’s drain and is linked to the primary winding of the transformer or inductor.
4. FB (Pin 4): The feedback pin monitors the output voltage and regulates the PWM duty cycle. It is connected to an opto-coupler or network to control the feedback loop.
These pins work together to ensure efficient power conversion and provide necessary protections and control features for various power supply applications.
