Description and Introduction

Phase Shift Resonant Controller The UC2876 is a high-performance switch-mode power supply controller manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 8V to 20V (operating), 36V (absolute max)  
- **Output Drive Current:** ±2A (peak)  
- **Switching Frequency Range:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 20-pin SOIC (D)  

### **Descriptions:**  
The UC2876 is a pulse-width modulation (PWM) controller designed for high-frequency power supply applications. It provides precise control for DC-DC converters, featuring high-speed switching capabilities and robust protection mechanisms.  

### **Features:**  
- **High-Speed PWM Control:** Optimized for high-frequency operation (up to 1MHz).  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Current-Limiting Protection:** Prevents damage from excessive load conditions.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Synchronous Rectification Support:** Enhances efficiency in power conversion.  
- **Adjustable Dead-Time Control:** Minimizes shoot-through in bridge topologies.
