Description and Introduction

High voltage start-up transition-mode PFC The L6563HTR is a transition-mode PFC controller manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Type:** Transition-Mode PFC Controller  
- **Package:** SO-8  
- **Operating Voltage Range:** 10.3V to 22V  
- **Start-Up Voltage:** 12.5V (typ)  
- **Quiescent Current:** 3.5mA (typ)  
- **Maximum Switching Frequency:** 300kHz  
- **Multiplier Input Voltage Range:** 0V to 3.8V  
- **ZCD Input Voltage Range:** -0.3V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The L6563HTR is a high-performance, transition-mode (boundary conduction mode) power factor correction (PFC) controller.  
- It is designed for boost pre-converters in AC-DC systems to comply with energy efficiency standards (e.g., EN61000-3-2).  
- It features a proprietary multiplier design for improved THD (Total Harmonic Distortion) performance.  

### **Features:**  
- **Transition-Mode Operation:** Ensures high power factor and low distortion.  
- **Low Start-Up & Operating Current:** Enhances efficiency.  
- **Overvoltage Protection (OVP):** Protects against output overvoltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper start-up and shutdown.  
- **Zero-Current Detection (ZCD):** Enables boundary conduction mode operation.  
- **Enhanced EMI Performance:** Reduces noise in high-frequency applications.  
- **Totem-Pole Output:** Supports high-current gate drive (600mA sink/source capability).  

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