- **Features:** Programmable dead-time, soft-start, cycle-by-cycle current limiting  

### **Descriptions:**
The UCC2892PWR is a high-efficiency active clamp PWM controller designed for power supply applications, including isolated DC-DC converters. It provides precise control for active clamp reset in forward converters, improving efficiency and reducing voltage stress on power switches.  

### **Features:**
- **Active Clamp Reset Control:** Optimizes transformer reset for improved efficiency.  
- **Programmable Dead-Time:** Adjustable dead-time between main and clamp switches.  
- **Voltage-Mode Control:** Ensures stable operation across varying loads.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Synchronizable Switching Frequency:** Allows synchronization to an external clock.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  

This information is based solely on the manufacturer's datasheet and technical documentation.
