Description and Introduction

Phase Shift Resonant Controller The UC2876N is a high-performance, fixed-frequency current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Control Method:** Current-mode PWM  
- **Frequency:** Fixed  
- **Input Voltage Range:** Typically operates with a wide input range (exact range should be verified in the datasheet)  
- **Output Drive:** Suitable for driving power MOSFETs  
- **Protection Features:** Includes overcurrent protection, undervoltage lockout (UVLO), and soft-start capability  
- **Package:** Typically comes in a PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The UC2876N is designed for switch-mode power supply (SMPS) applications, providing precise regulation and efficient power conversion. It integrates key control and protection features to enhance system reliability.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation  
- **Fixed-Frequency Operation:** Ensures predictable switching behavior  
- **Soft-Start Function:** Reduces inrush current during startup  
- **UVLO Protection:** Ensures proper operation under low-voltage conditions  
- **High-Current Totem-Pole Output:** Directly drives power MOSFETs  

For exact electrical characteristics and application details, refer to the official TI datasheet.
