- **Propagation Delay:** 50ns  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 16-pin SOIC (D)  

### **Descriptions:**  
The UC3823AQ is a pulse-width modulation (PWM) controller designed for high-frequency switching power supplies. It features fast response times, high drive capability, and precise duty cycle control, making it suitable for applications such as DC-DC converters, inverters, and motor control.  

### **Features:**  
- **High-Speed Operation:** Optimized for switching frequencies up to 1MHz.  
- **Precision Reference:** 5.1V ±1% trimmed bandgap reference.  
- **Soft-Start Capability:** Adjustable soft-start function for controlled startup.  
- **Dual Under-Voltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Current Limiting:** Built-in current sense comparator for overcurrent protection.  
- **Totem Pole Outputs:** High-current (2A) push-pull outputs for driving power MOSFETs.  
- **Synchronization:** Allows synchronization with an external clock.  
- **Error Amplifier:** Wide-bandwidth (5MHz) for fast transient response.
