Description and Introduction

UCC289x Current Mode Active Clamp PWM Controller The UCC2892 is a high-performance current-mode PWM controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 8.5V to 18V (operating)  
- **Maximum Duty Cycle:** Up to 100%  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Control Method:** Current-Mode PWM  
- **Output Drive Capability:** 1A peak gate drive  
- **Package Options:** SOIC-8, PDIP-8  

### **Descriptions:**  
The UCC2892 is a versatile PWM controller designed for high-efficiency power supply applications. It provides precise current-mode control, enabling stable operation in various topologies, including flyback, forward, and buck converters. It includes features like soft-start, cycle-by-cycle current limiting, and undervoltage lockout (UVLO) for robust performance.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures reliable operation under low input voltage conditions.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **High-Current Gate Drive (1A Peak):** Supports fast switching of power MOSFETs.  
- **Wide Operating Temperature Range:** Suitable for industrial and automotive applications.
