### **Descriptions:**  
The UC2823ADW is a high-performance PWM controller designed for switching power supplies. It features fast response, high-frequency operation, and precise control for voltage-mode applications. It includes an error amplifier, oscillator, soft-start, and protection features like undervoltage lockout (UVLO).  

### **Features:**  
- High-speed PWM operation (up to 1MHz)  
- Adjustable dead-time control  
- Precision reference voltage (5V ±1%)  
- Dual pulse-by-pulse current limiting  
- Synchronization capability  
- Low startup current (<1mA)  
- Thermal shutdown protection  

This controller is commonly used in DC-DC converters, power supplies, and motor control applications.
