Description and Introduction

Green Phase-Shifted Full-Bridge Controller with Synchronous Rectification 24-TSSOP -40 to 125 The UCC28950PWR is a phase-shifted full-bridge controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Package:** TSSOP-20  
- **Topology:** Phase-Shifted Full-Bridge (PSFB)  
- **Control Method:** Voltage Mode or Current Mode  
- **Input Voltage Range:** 4.5V to 15V (VDD)  
- **Switching Frequency Range:** 50kHz to 1MHz  
- **Output Drive Current:** ±4A (peak)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Duty Cycle Range:** 0% to 100% (adjustable)  
- **Features:** Synchronous Rectifier Control, Adaptive Delay, Programmable Dead Time  

### **Descriptions:**  
The UCC28950PWR is a high-performance phase-shifted full-bridge controller designed for high-power DC-DC converters. It provides precise control for power stages in applications such as telecom, industrial, and server power supplies. The device supports both voltage-mode and current-mode control, along with adaptive delay management for synchronous rectifiers to improve efficiency.  

### **Features:**  
- **Phase-Shifted Full-Bridge Control:** Enables zero-voltage switching (ZVS) for reduced switching losses.  
- **Programmable Dead Time:** Optimizes efficiency by adjusting dead time between switches.  
- **Synchronous Rectifier Control:** Supports adaptive timing for improved efficiency in secondary-side rectification.  
- **Frequency Synchronization:** Allows synchronization to an external clock.  
- **Soft-Start & Soft-Stop:** Reduces inrush current during startup and shutdown.  
- **Protection Features:** Includes overcurrent protection (OCP), undervoltage lockout (UVLO), and thermal shutdown.  
- **Adjustable Switching Frequency:** Configurable from 50kHz to 1MHz.  

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