Description and Introduction

Advanced transition-mode PFC controller The L6563ATR is a transition-mode PFC controller manufactured by STMicroelectronics (STM). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** STMicroelectronics (STM)  
- **Type:** Transition-Mode PFC Controller  
- **Package:** SO-8  
- **Input Voltage Range:** Up to 600V  
- **Operating Frequency:** Adjustable, up to 300kHz  
- **Start-Up Current:** 60µA (typical)  
- **Quiescent Current:** 4mA (typical)  
- **Output Drive Capability:** 600mA source / 800mA sink  
- **Reference Voltage:** 2.5V (±1% accuracy)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The L6563ATR is a high-performance PFC (Power Factor Correction) controller designed for transition-mode (boundary conduction mode) operation. It is optimized for pre-converter stages in AC-DC power supplies, ensuring compliance with energy efficiency standards.  

### **Features:**  
- **Transition-Mode Operation:** Ensures high power factor and low THD (Total Harmonic Distortion).  
- **Multiplier-Enhanced Input:** Improves distortion at low input voltages.  
- **Overvoltage Protection (OVP):** Prevents output overvoltage conditions.  
- **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 Power Consumption:** Optimized for energy-efficient designs.  
- **Totem-Pole Output:** High current drive capability for fast MOSFET switching.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
