Description and Introduction

Phase Shift Resonant Controller The UC3879DW is a Phase Shift Resonant Controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage (VCC):** 12V to 20V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-20 (DW)  
- **Switching Frequency:** Up to 2MHz  
- **Output Drive Current:** 2A (peak)  
- **Control Method:** Phase-Shifted PWM  
- **Soft-Start Capability:** Yes  
- **Under-Voltage Lockout (UVLO):** Yes  

### **Descriptions:**  
The UC3879DW is a high-performance resonant mode controller designed for phase-shifted full-bridge and half-bridge power converters. It provides precise control for zero-voltage switching (ZVS) applications, improving efficiency in high-power systems.  

### **Features:**  
- Adjustable dead-time control for ZVS operation  
- Programmable oscillator frequency  
- Error amplifier with bandwidth compensation  
- Soft-start and shutdown functionality  
- Dual-mode overcurrent protection  
- Compatible with voltage-mode and current-mode topologies  

For detailed datasheets and application notes, refer to Texas Instruments' official documentation.
