Description and Introduction

Resonant Lamp Ballast Controller The UC3872MTR is a Phase Shift Resonant Controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UC3872MTR  
- **Type:** Phase Shift Resonant Controller  
- **Package:** SOIC-20  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** Up to 20V  
- **Output Current:** 100mA (sink/source)  
- **Switching Frequency:** Adjustable, supports high-frequency operation  
- **Control Method:** Phase-shifted PWM  

### **Descriptions:**  
The UC3872MTR is designed for high-efficiency power conversion applications, particularly in resonant and phase-shifted full-bridge topologies. It provides precise control over switching transitions to minimize losses and improve efficiency in power supplies.  

### **Features:**  
- **Phase-Shifted PWM Control:** Enables soft switching for reduced switching losses.  
- **Adjustable Dead Time:** Optimizes switching transitions for efficiency.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Programmable Oscillator:** Allows flexible frequency setting.  
- **Error Amplifier:** Supports closed-loop feedback control.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **High-Current Output Drivers:** Capable of driving power MOSFETs or IGBTs directly.  

This information is based on TI's official documentation for the UC3872MTR. For detailed application notes or additional specifications, refer to the manufacturer's datasheet.
