Description and Introduction

Combo IC for PFC and ballast control The part **L6585D** is manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Type:** High-voltage resonant controller  
- **Operating Voltage Range:** Up to 600V  
- **Frequency Range:** Adjustable, typically up to several hundred kHz  
- **Package:** SO-16 (Surface Mount)  
- **Control Method:** Resonant mode (ZVS/ZCS)  
- **Protection Features:** Overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown  

### **Descriptions:**  
The **L6585D** is a high-voltage resonant controller designed for power supply applications, particularly in LLC resonant half-bridge topologies. It ensures efficient power conversion with soft-switching techniques (Zero Voltage Switching - ZVS and Zero Current Switching - ZCS), reducing switching losses.  

### **Features:**  
- **Integrated high-voltage startup circuit**  
- **Adaptive dead-time control** for optimized efficiency  
- **Adjustable operating frequency** for resonant operation  
- **Brown-out protection** for input voltage monitoring  
- **Soft-start function** to limit inrush current  
- **Low standby power consumption**  

This IC is commonly used in **AC-DC adapters, LED drivers, and industrial power supplies**.
