Description and Introduction

Current Mode Active Clamp PWM Controller 20-QFN -40 to 105 The UCC2897RTJR is a high-performance 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)  
- **Part Number:** UCC2897RTJR  
- **Package:** QFN-32  
- **Type:** Phase-Shifted Full-Bridge PWM Controller  
- **Operating Temperature Range:** -40°C to +125°C  
- **Supply Voltage (VDD):** 10V to 18V  
- **Switching Frequency Range:** 50kHz to 1MHz  
- **Output Drive Current (Source/Sink):** 2A (Peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Control Method:** Voltage-Mode PWM with Phase-Shifting  

### **Descriptions:**  
The UCC2897RTJR is designed for high-efficiency, high-power DC-DC converters. It provides advanced phase-shifting control for full-bridge topologies, enabling zero-voltage switching (ZVS) to minimize switching losses. The device integrates multiple protection features, including overcurrent protection, undervoltage lockout (UVLO), and programmable dead-time control.

### **Features:**  
- **Phase-Shifted Full-Bridge Control:** Enables ZVS for improved efficiency.  
- **Adjustable Switching Frequency:** Configurable from 50kHz to 1MHz.  
- **Programmable Dead-Time Control:** Optimizes ZVS transitions.  
- **Voltage-Mode Control:** Simplifies loop compensation.  
- **Integrated Protections:**  
  - Overcurrent protection (OCP)  
  - Undervoltage lockout (UVLO)  
  - Soft-start capability  
- **High-Current Gate Drivers:** 2A peak output drive for fast MOSFET switching.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.
