Description and Introduction

Advanced Current-Mode Active Clamp PWM Controller 20-TSSOP -40 to 125 The UCC2897APW is a phase-shifted full-bridge PWM controller manufactured by Texas Instruments (TI) and Burr-Brown (BB).  

### **Specifications:**  
- **Control Method:** Phase-shifted full-bridge PWM  
- **Operating Frequency:** Up to 1 MHz  
- **Output Drive Configuration:** Dual 2A peak current totem-pole outputs  
- **Supply Voltage (VDD):** 15V (max)  
- **UVLO (Undervoltage Lockout):** 9.25V (turn-on), 8.75V (turn-off)  
- **Duty Cycle Range:** 0% to 100%  
- **Package:** TSSOP-20 (PW)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UCC2897APW is designed for high-power applications, providing precise control for phase-shifted full-bridge converters. It features adaptive delay control to minimize circulating current and improve efficiency.  

### **Features:**  
- Adaptive delay control for zero-voltage switching (ZVS)  
- Programmable dead time and delay  
- Soft-start capability  
- Synchronizable oscillator  
- Error amplifier with reference voltage  
- Current-limiting protection  
- Under-voltage lockout (UVLO)

Description and Introduction

Advanced Current-Mode Active Clamp PWM Controller 20-TSSOP -40 to 125 The UCC2897APW is a high-performance phase-shifted full-bridge PWM controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Part Number:** UCC2897APW  
- **Package:** TSSOP-20  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 9V to 17V  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Output Drive Current:** ±4A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Control Method:** Phase-shifted full-bridge PWM  

### **Descriptions:**  
The UCC2897APW is a phase-shifted full-bridge controller designed for high-efficiency power conversion applications. It provides precise control for zero-voltage switching (ZVS) in full-bridge topologies, improving efficiency and reducing switching losses. It includes adaptive delay control, programmable dead time, and soft-start functionality.  

### **Features:**  
- **Zero-Voltage Switching (ZVS):** Optimizes efficiency by minimizing switching losses.  
- **Adaptive Delay Control:** Ensures optimal timing for ZVS transitions.  
- **Programmable Dead Time:** Adjustable to prevent shoot-through in power switches.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Synchronizable Oscillator:** Allows synchronization with an external clock.  
- **Under-Voltage Lockout (UVLO):** Protects the system during low input voltage conditions.  
- **Error Amplifier:** Provides feedback loop control for voltage regulation.  
- **Overcurrent Protection:** Enhances system reliability.  

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