Description and Introduction

IMPROVED HIGH-VOLTAGE RESONANT CONTROLLER The L6599A 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  

### **Specifications:**  
- **Input Voltage Range (VCC):** 9.6V to 16V  
- **Operating Frequency Range:** Up to 500kHz  
- **High-Voltage Rail:** Up to 600V (floating)  
- **Output Current (Gate Drivers):** 400mA (source), 800mA (sink)  
- **Dead Time Control:** Adjustable  
- **Protection Features:**  
  - Overcurrent protection (OCP)  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
  - Latched or auto-restart fault management  

### **Descriptions:**  
The L6599A is a double-ended resonant controller designed for LLC resonant half-bridge topologies. It integrates high-voltage circuitry and gate drivers, making it suitable for high-efficiency power supply applications. The device ensures soft-switching operation, reducing switching losses and improving efficiency.  

### **Features:**  
- **High-Voltage Startup Circuit:** Eliminates the need for an external startup resistor.  
- **Adjustable Switching Frequency:** Allows optimization for different resonant tank designs.  
- **Precise Dead-Time Control:** Ensures zero-voltage switching (ZVS) for reduced losses.  
- **Synchronization Capability:** Can be synchronized to an external clock.  
- **Burst Mode Operation:** Enhances efficiency at light loads.  
- **SO16N Package:** Compact and suitable for space-constrained designs.  

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