FAN7930CMX-ON Typical application Circuitry

FAN7930CMX-ON

The FAN7930CMX-ON is a Power Factor Correction (PFC) controller chip designed to enhance the efficiency of AC-DC power supplies by improving their power factor. Here's a detailed overview:

Functionality: The FAN7930CMX-ON operates in boundary conduction mode (BCM), optimizing efficiency by reducing switching losses. It regulates the input current to align with the input voltage waveform, thereby achieving a higher power factor.

Applications: This chip is commonly employed in AC-DC power supplies for LED lighting, LCD monitors, and other consumer electronics that demand efficient power conversion and a compact design.

Parameters: The FAN7930CMX-ON supports a wide operating voltage range, typically 9V to 25V, and a maximum switching frequency of 65kHz. It has functions including under-voltage lockout, over-current protection, and over-voltage protection.

Circuit Design for an LCD Monitor Power Supply:

1. Input Capacitor: To filter out noise and lessen EMI, connect a capacitor between the AC input and ground.

2. Bridge Rectifier: Use a bridge rectifier to convert the AC input to DC.

3. Boost Inductor: Attach a boost inductor between the rectified DC output and the drain (Pin 6) of the external PFC MOSFET controlled by the FAN7930CMX-ON.

4. Voltage Sensing: Implement a resistor divider from the rectified DC output to the VSENSE (Pin 3) of the FAN7930CMX-ON to monitor the input voltage.

5. Current Sensing: Place a sensing resistor between the source of the PFC MOSFET and ground, connecting the resulting sense voltage to the ISENSE (Pin 2) of the FAN7930CMX-ON.

6. Gate Drive: Link the GATE (Pin 1) of the FAN7930CMX-ON to the gate of the PFC MOSFET to regulate its switching behavior.

7. Feedback Loop: Create a feedback loop using an optocoupler and a TL431 precision reference to relay output voltage information back to the FAN7930CMX-ON for regulation.

Design Considerations:

1. Component Selection: Choose the boost inductor and current sensing resistor values carefully to ensure optimal PFC operation and efficiency.

2. Thermal Management: Implement appropriate cooling solutions for the PFC MOSFET and the FAN7930CMX-ON, especially in high-power applications.

3. Protection Features: Configure the protection features of the FAN7930CMX-ON to prevent damage to the power supply under abnormal conditions.

4. EMI Mitigation: Design the input filter and the PCB layout to minimize EMI and comply with regulatory standards.

By following these guidelines and adapting the design to the specific requirements of your LCD monitor power supply application, you can effectively utilize the FAN7930CMX-ON in your power supply design.
