Description and Introduction

Highly Integrated Green- Mode PWM Controller The FAN6754MRMY is a power switch controller IC manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its key specifications:

1. **Function**: Primary-side PWM controller for flyback converters.  
2. **Topology**: Supports quasi-resonant (QR) operation for improved efficiency.  
3. **Input Voltage Range**: Designed for universal AC input (85–265VAC).  
4. **Switching Frequency**: Adjustable, typically up to 130 kHz.  
5. **Features**:  
   - Built-in high-voltage startup circuit.  
   - Frequency jittering for reduced EMI.  
   - Overvoltage (OVP), overload (OLP), and over-temperature (OTP) protection.  
   - Cycle-by-cycle current limiting.  
6. **Package**: 8-pin SOIC (MRMY suffix).  
7. **Applications**: Used in AC/DC power supplies for adapters, LED drivers, and auxiliary power supplies.
