High Speed PWM Controller The UC3825AQ is a high-speed PWM controller manufactured by Texas Instruments (TI) and Burr-Brown (BB).  

### **Specifications:**  
- **Output Configuration:** Push-Pull  
- **Topology:** Boost, Flyback, Forward  
- **Switching Frequency:** Up to 1MHz  
- **Supply Voltage (VCC):** 10V to 30V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current (Source/Sink):** 2A Peak  
- **Package:** 16-Pin SOIC (D)  

### **Descriptions:**  
The UC3825AQ is a high-performance pulse-width modulation (PWM) controller optimized for high-frequency switching power supplies. It features fast response times, precise duty cycle control, and robust protection mechanisms.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Adjustable Dead-Time Control:** Allows precise timing adjustments.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Double-Pulse Suppression:** Prevents multiple pulses in a single cycle.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Error Amplifier:** Provides stable feedback loop control.  
- **Synchronous Operation:** Can be synchronized to an external clock.  
- **Current-Limiting Protection:** Enhances system reliability.  

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