### **Descriptions:**  
The UC2825Q is a high-performance pulse-width modulation (PWM) controller designed for high-frequency power supply applications. It features fast response times, high output drive capability, and precise duty cycle control, making it suitable for demanding power conversion systems.  

### **Features:**  
- **High-Speed Operation:** Optimized for switching frequencies up to 1 MHz  
- **Precision Reference:** 5.1V ±1% trimmed bandgap reference  
- **Dual Output Drivers:** Capable of sourcing/sinking 2A peak current  
- **Programmable Dead-Time Control:** Adjustable for optimal efficiency  
- **Synchronizable Oscillator:** Allows for multi-phase operation  
- **Error Amplifier:** Wide bandwidth for fast transient response  
- **Soft-Start Function:** Reduces inrush current during startup  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range  
- **Current-Limiting Capability:** Protects against overloads  

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