Description and Introduction

Resonant Lamp Ballast Controller 16-SSOP 0 to 70 The UC3872MTRG4 is a Phase-Shifted Full-Bridge PWM Controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** 20-SOIC  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 15V (Max)  
- **Output Current:** 2A (Peak)  
- **Switching Frequency:** Up to 1MHz  
- **Control Method:** Voltage Mode PWM  
- **Topology:** Phase-Shifted Full-Bridge  

### **Descriptions:**  
The UC3872MTRG4 is designed for high-power applications, providing precise phase-shifted PWM control for full-bridge converters. It optimizes efficiency by reducing switching losses through zero-voltage switching (ZVS) techniques.  

### **Features:**  
- **Phase-Shifted PWM Control:** Enables ZVS for reduced switching losses.  
- **Adjustable Dead-Time:** Optimizes switching transitions.  
- **Programmable Oscillator:** Allows frequency adjustment.  
- **Soft-Start Capability:** Prevents inrush current.  
- **Under-Voltage Lockout (UVLO):** Ensures proper startup.  
- **Error Amplifier:** Supports closed-loop feedback.  
- **Synchronous Rectifier Control:** Enhances efficiency in secondary-side regulation.  

This device is commonly used in telecom, industrial, and high-power DC-DC converters.
