Description and Introduction

Boundary Mode PFC Controller The FAN6961 is a critical conduction mode (CrM) PFC controller manufactured by Fairchild Semiconductor. Here are its key specifications:

- **Input Voltage Range**: Operates with a wide input voltage range suitable for universal AC line applications (typically 85V to 265V AC).
- **Output Voltage**: Supports output voltages up to 400V DC.
- **Switching Frequency**: Operates in critical conduction mode with variable frequency, typically ranging from tens of kHz to over 100 kHz depending on load and input conditions.
- **Control Method**: Uses average current mode control for high power factor correction (PFC).
- **Features**: Includes over-voltage protection (OVP), under-voltage lockout (UVLO), and soft-start functionality.
- **Package**: Available in an 8-pin SOIC package.
- **Applications**: Designed for use in AC-DC power supplies, LED lighting, and other applications requiring power factor correction.

These specifications are based on Fairchild Semiconductor's documentation for the FAN6961.
