- **Propagation Delay (Typical):** 20ns  
- **Rise Time (Typical):** 10ns  
- **Fall Time (Typical):** 8ns  

### **Descriptions:**
- The **UCD7231RTJR** is a high-speed, dual-channel MOSFET driver designed for synchronous buck converters.  
- It provides high peak current drive capability for efficient switching of power MOSFETs.  
- The device includes adaptive dead-time control to prevent shoot-through in half-bridge configurations.  
- It is optimized for high-frequency switching applications.  

### **Features:**
- **Dual Independent Drivers:** Supports two non-inverting outputs.  
- **High Drive Strength:** 4A source/sink current capability.  
- **Wide Supply Voltage Range:** 4.5V to 15V for flexibility in power supply design.  
- **Adaptive Dead-Time Control:** Prevents cross-conduction in half-bridge topologies.  
- **Fast Switching Speeds:** Low propagation delay and rise/fall times for high efficiency.  
- **TTL/CMOS Input Logic:** Compatible with standard control signals.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Small Footprint:** 20-pin WQFN package for space-constrained applications.  

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