- **Propagation Delay:** 50ns  

### **Descriptions:**  
The UC3823DWTR is a high-performance pulse-width modulation (PWM) controller designed for power supply applications. It features fast response times, high-frequency operation, and robust protection features, making it suitable for switch-mode power supplies (SMPS), DC-DC converters, and motor control systems.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Precision Reference:** 5.1V ±1% trimmed bandgap reference.  
- **Dual Outputs:** Two totem-pole outputs for driving power MOSFETs or IGBTs.  
- **Programmable Deadtime Control:** Adjustable deadtime between outputs.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Current Limiting:** Features cycle-by-cycle current limiting.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Error Amplifier:** High-gain, wide-bandwidth amplifier for feedback control.  
- **Synchronization Capability:** Allows synchronization to an external clock.  

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