Description and Introduction

HIGH VOLTAGE DRIVER FOR CFL The L6567D is a transition mode PFC controller manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Voltage Regulation:** Adjustable (typically up to 400V DC)  
- **Switching Frequency:** Transition mode (variable frequency)  
- **Operating Frequency Range:** Up to 300 kHz  
- **Start-Up Current:** < 50 µA  
- **Quiescent Current:** < 4 mA  
- **Maximum Duty Cycle:** 94%  
- **Driver Output Current (Source/Sink):** ±400 mA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-8  

### **Description:**  
The L6567D is a high-performance power factor correction (PFC) controller designed for transition mode (boundary conduction mode) operation. It is optimized for pre-regulators in AC-DC converters, ensuring high power factor and low harmonic distortion.  

### **Features:**  
- **Transition Mode Operation:** Ensures high efficiency and reduced switching losses.  
- **Low Distortion & High PF:** Achieves near-unity power factor (PF > 0.99).  
- **Overvoltage Protection (OVP):** Prevents excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper start-up and shutdown.  
- **Zero-Current Detection (ZCD):** Enables boundary conduction mode operation.  
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Low Standby Power Consumption:** Suitable for energy-efficient applications.  
- **Enhanced EMI Performance:** Due to quasi-resonant operation.
