Description and Introduction

Current Mode Active Clamp PWM Controller The UCC2897PW 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 +85°C  
- **Input Voltage (VCC):** 10V to 18V (recommended)  
- **Maximum Switching Frequency:** 1MHz  
- **Control Method:** Phase-shifted PWM  
- **Output Drive Current:** ±2A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Soft-Start Capability:** Yes  
- **Under-Voltage Lockout (UVLO):** Yes  

### **Descriptions:**  
The UCC2897PW is a high-performance phase-shifted full-bridge controller designed for high-power DC-DC converters. It provides precise PWM control for efficient power conversion in applications such as telecom, industrial, and server power supplies. The device supports zero-voltage switching (ZVS) to minimize switching losses and improve efficiency.  

### **Features:**  
- **Phase-Shifted Full-Bridge Control:** Enables ZVS operation for reduced switching losses.  
- **Programmable Dead-Time Control:** Optimizes efficiency by adjusting dead time.  
- **Adaptive Delay Control:** Enhances ZVS performance across load variations.  
- **Synchronizable Oscillator:** Allows synchronization with external clocks.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Error Amplifier:** Supports closed-loop feedback control.  

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