Description and Introduction

Phase Shift Resonant Controller The UC3879N is a Phase Shift Resonant Controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 12V to 20V  
- **Operating Frequency Range:** Up to 2MHz  
- **Output Drive Current:** 2A (peak)  
- **Supply Current:** 35mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The UC3879N is a high-performance phase shift resonant controller designed for full-bridge or half-bridge power converter topologies. It provides precise control for zero-voltage switching (ZVS) applications, improving efficiency in power conversion systems.  

### **Features:**  
- **Programmable Output Dead Time:** Adjusts dead time between outputs for optimized ZVS.  
- **Voltage-Mode or Current-Mode Control:** Supports both control schemes.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Error Amplifier:** Integrated for feedback loop control.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Overcurrent Protection:** Enhances system reliability.  

This controller is commonly used in high-power applications such as telecom power supplies, industrial converters, and server power systems.
