Description and Introduction

Phase Shift Resonant Controller The UC3879DWTR is a phase-shifted PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Phase-shifted full-bridge or half-bridge  
- **Operating Frequency Range:** Up to 2 MHz  
- **Output Drive:** Dual 2A totem-pole outputs  
- **Supply Voltage (VCC):** 12V to 20V (recommended)  
- **Maximum Duty Cycle:** Adjustable, near 50% per output  
- **Package:** SOIC-20 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UC3879DWTR is designed for high-frequency, high-efficiency power conversion applications. It provides precise phase-shift control for full-bridge or half-bridge converters, enabling zero-voltage switching (ZVS) to minimize switching losses.  

### **Features:**  
- Adjustable dead-time control for ZVS optimization  
- Programmable oscillator frequency  
- Soft-start capability  
- Under-voltage lockout (UVLO) protection  
- Error amplifier for closed-loop control  
- Compatible with voltage-mode or current-mode control  

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