Description and Introduction

Current Mode Active Clamp PWM Controller The UCC2897PWR is a phase-shifted full-bridge controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** TSSOP-20  
- **Operating Temperature Range:** -40°C to +125°C  
- **Input Voltage Range (VDD):** 10V to 18V  
- **Switching Frequency Range:** Adjustable, up to 1MHz  
- **Output Drive Current:** ±4A (peak)  
- **Control Method:** Voltage-mode PWM with phase-shifted full-bridge topology  
- **Duty Cycle Range:** 0% to 100%  
- **Protection Features:** Overcurrent protection, soft-start, programmable dead-time control  

### **Descriptions:**  
The UCC2897PWR is a high-performance phase-shifted full-bridge controller designed for high-power DC-DC converters. It provides precise control for power conversion applications, enabling efficient power delivery with reduced switching losses. The device supports synchronous rectification and includes features for enhanced reliability in industrial and telecom applications.  

### **Features:**  
- **Phase-Shifted Full-Bridge Control:** Reduces switching losses and improves efficiency.  
- **Adaptive Delay Control:** Optimizes dead-time for synchronous rectifiers.  
- **Programmable Soft-Start:** Prevents inrush current during startup.  
- **Voltage-Mode PWM:** Ensures stable operation under varying load conditions.  
- **Integrated Protections:** Includes overcurrent shutdown and undervoltage lockout (UVLO).  
- **Adjustable Switching Frequency:** Allows optimization for different power stages.  
- **High-Current Gate Drivers:** Supports MOSFETs with ±4A peak drive capability.  

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