Description and Introduction

UCC289x Current Mode Active Clamp PWM Controller 16-SOIC -40 to 85 The UCC2892DG4 is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Flyback, Forward  
- **Control Method:** Current Mode  
- **Frequency Range:** Up to 1 MHz  
- **Input Voltage (VCC):** 8.5V to 16V (operating), 20V (max)  
- **Output Voltage:** Adjustable  
- **Duty Cycle Range:** Up to 50% (max)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC2892DG4 is designed for high-efficiency power supply applications, providing precise control in isolated DC-DC converters. It features cycle-by-cycle current limiting, soft-start, and under-voltage lockout (UVLO) for enhanced protection.  

### **Features:**  
- **Current-Mode Control:** Improves transient response and simplifies loop compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within safe voltage limits.  
- **Cycle-by-Cycle Current Limiting:** Protects against overload conditions.  
- **High-Frequency Operation:** Supports switching frequencies up to 1 MHz for compact designs.  
- **Low Startup Current:** Reduces power consumption during startup.  

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