### **Descriptions:**  
The UCC2894DR is a high-performance PWM controller designed for power supply applications. It provides precise regulation and high efficiency in various topologies, including flyback, forward, and push-pull converters. The device integrates advanced features such as programmable soft-start, cycle-by-cycle current limiting, and adjustable dead-time control.  

### **Features:**  
- **Peak Current-Mode Control:** Ensures stable operation and fast transient response.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Adjustable Dead-Time Control:** Optimizes efficiency in synchronous rectifier applications.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Wide Input Voltage Range:** Supports 4.5V to 12V for flexibility in design.  
- **High-Frequency Operation:** Suitable for high-density power supplies (up to 1MHz).  
- **Synchronous Rectifier Control:** Enhances efficiency in DC-DC converters.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.
