### **Descriptions:**
The UCC2893DR is a high-performance synchronous buck controller designed for DC-DC conversion applications. It supports voltage-mode control with adjustable switching frequency and provides efficient power conversion with synchronous rectification. The device includes features such as soft-start, programmable dead-time control, and overcurrent protection.

### **Features:**
- **Wide Input Voltage Range (4.5V to 18V)** – Suitable for various power supply applications.  
- **Adjustable Switching Frequency (up to 1MHz)** – Allows optimization for efficiency and component size.  
- **Synchronous Rectification** – Improves efficiency by reducing conduction losses.  
- **Programmable Dead-Time Control** – Enhances efficiency by minimizing shoot-through currents.  
- **Adjustable Soft-Start** – Reduces inrush current during startup.  
- **Voltage-Mode PWM Control** – Provides stable regulation.  
- **Overcurrent Protection** – Enhances system reliability.  
- **SOIC-8 Package** – Compact and suitable for space-constrained designs.
