Description and Introduction

BiCMOS Advanced Phase Shift Resonant Controller The UCC2895 is a high-performance phase-shifted full-bridge controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 15V (VDD)  
- **Operating Frequency Range:** Up to 1MHz  
- **Output Drive Current:** ±2A (peak)  
- **Duty Cycle Range:** 0% to 100% (adjustable)  
- **Soft-Start Time:** Programmable  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SOIC-20, TSSOP-20  

### **Descriptions:**  
The UCC2895 is designed for high-efficiency, phase-shifted full-bridge DC-DC power converters. It provides advanced control for zero-voltage switching (ZVS) topologies, reducing switching losses and improving efficiency. The device includes adaptive delay control, programmable dead-time, and synchronous rectifier timing for optimal performance in high-power applications.  

### **Features:**  
- **Zero-Voltage Switching (ZVS) Control:** Enables efficient power conversion by minimizing switching losses.  
- **Adaptive Delay Control:** Adjusts timing dynamically to maintain ZVS under varying load conditions.  
- **Programmable Dead-Time:** Allows optimization of switching transitions.  
- **Synchronous Rectifier Control:** Supports external MOSFET drivers for improved efficiency.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Overcurrent Protection:** Includes cycle-by-cycle current limiting.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Bidirectional Sync Capability:** Supports synchronization with external clock signals.  

This information is sourced from the official Texas Instruments datasheet for the UCC2895.
