Description and Introduction

High-voltage resonant controller The L6599D is a high-voltage resonant controller manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics  

### **Description:**  
The L6599D is a double-ended resonant controller designed for high-efficiency resonant power supplies. It is optimized for half-bridge topologies with resonant conversion, making it suitable for applications like AC-DC adapters, LED drivers, and industrial power supplies.  

### **Key Features:**  
- **Voltage Range:**  
  - High-voltage rail up to 600V  
  - Supply voltage (Vcc) range: 8.6V to 16V (with UVLO protection)  

- **Frequency Control:**  
  - Adjustable switching frequency (up to 500kHz)  
  - Soft-start and frequency-shift control for smooth operation  

- **Protection Features:**  
  - Overcurrent protection (OCP) with latched or auto-restart mode  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
  - Interlocking and dead-time control for half-bridge MOSFETs  

- **Other Features:**  
  - Integrated high-voltage startup circuit  
  - Adjustable dead time for optimized efficiency  
  - Synchronization capability for multi-phase operation  

### **Applications:**  
- AC-DC converters for adapters and power supplies  
- LED lighting drivers  
- Industrial and telecom power systems  

### **Package:**
