Description and Introduction

High Speed PWM Controller The UC3825N is a high-speed PWM controller manufactured by Texas Instruments.  

### **Specifications:**  
- **Input Voltage (VCC):** 8V to 35V  
- **Output Current (Source/Sink):** 2A peak  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- Designed for high-frequency switching power supplies.  
- Features a high-speed PWM comparator for fast response.  
- Includes a precision reference voltage (5.1V ±1%).  
- Provides soft-start functionality.  
- Supports voltage-mode and current-mode control.  

### **Features:**  
- **High-Speed Operation:** Optimized for fast switching applications.  
- **Dual Outputs:** Totem-pole outputs for driving power MOSFETs.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Programmable Dead-Time Control:** Prevents shoot-through in half-bridge configurations.  
- **Error Amplifier:** Wide bandwidth for improved transient response.  
- **Synchronization Capability:** Allows multiple controllers to sync to a single clock.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official Texas Instruments documentation.
