Description and Introduction

CURRENT-MODE ACTIVE CLAMP PWM CONTROLLER The UCC2892PWRG4 is a high-performance active clamp/reset PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Active clamp/reset  
- **Control Method:** Voltage mode PWM  
- **Frequency Range:** Up to 1 MHz  
- **Input Voltage (VDD):** 4.5V to 12V  
- **Output Drive Current:** ±1.5A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-20 (PowerPAD™)  

### **Descriptions:**  
The UCC2892PWRG4 is designed for high-efficiency power conversion applications, particularly in active clamp/reset forward converters. It integrates advanced features to optimize performance, including programmable dead-time control, soft-start, and cycle-by-cycle current limiting.  

### **Features:**  
- **Programmable Dead-Time Control:** Ensures optimal switching transitions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Enhances system protection.  
- **Synchronous Rectifier Control:** Improves efficiency in secondary-side regulation.  
- **Adjustable Switching Frequency:** Up to 1 MHz for compact designs.  
- **Integrated High-Current Gate Drivers:** Supports fast MOSFET switching.  
- **Undervoltage Lockout (UVLO):** Ensures reliable operation.  

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