Description and Introduction

Current Mode Active Clamp PWM Controller The UCC2893D is a high-performance synchronous rectifier controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range (VDD):** 4.5V to 15V  
- **Operating Frequency:** Up to 1MHz  
- **Driver Output Current (Source/Sink):** 2A (Peak)  
- **Propagation Delay (Turn-On/Turn-Off):** 25ns (Typical)  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC2893D is designed to control external N-channel MOSFETs in synchronous rectification applications, improving efficiency in power converters. It features adaptive timing control to minimize body diode conduction losses and supports both forward and flyback converter topologies.  

### **Features:**  
- Adaptive dead-time control for optimal efficiency  
- Fast propagation delays for high-frequency operation  
- Under-voltage lockout (UVLO) protection  
- Low quiescent current (1.5mA typical)  
- Compatible with isolated and non-isolated power supplies  

This device is commonly used in telecom, industrial, and computing power supply applications.
