Description and Introduction

Secondary Side Average Current Mode Controller The UCC2839D is a high-speed, dual-channel MOSFET driver manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Type:** Dual-Channel MOSFET Driver  
- **Supply Voltage (VDD):** 4.5V to 15V  
- **Peak Output Current:** ±4A  
- **Propagation Delay (Typical):** 25ns  
- **Rise/Fall Time (10% to 90%):** 15ns (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC2839D is designed to drive high-side and low-side N-channel MOSFETs in synchronous rectification or half-bridge applications. It features fast switching speeds and high peak output current, making it suitable for high-frequency power converters.  

### **Features:**  
- **Dual Independent Outputs:** Can drive two MOSFETs independently.  
- **High-Speed Switching:** Optimized for fast transitions with low propagation delay.  
- **4A Peak Output Current:** Capable of driving large MOSFETs efficiently.  
- **Wide Supply Voltage Range:** Operates from 4.5V to 15V.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation by disabling outputs when VDD is too low.  
- **Compatible with TTL/CMOS Inputs:** Easy interfacing with logic-level signals.  

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