Description and Introduction

High Speed PWM Controller The UC3825 is a high-speed PWM controller manufactured by Texas Instruments. Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 8V to 35V  
- **Operating Frequency:** Up to 1MHz  
- **Output Drive Current:** ±2A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Propagation Delay:** 50ns  
- **Error Amplifier Bandwidth:** 12MHz  
- **Soft-Start Control:** Adjustable  
- **Operating Temperature Range:** -40°C to +85°C  

### **Description:**  
The UC3825 is a pulse-width modulation (PWM) controller designed for high-frequency switching power supplies. It features high-speed performance, precision control, and robust protection mechanisms, making it suitable for applications like DC-DC converters, inverters, and motor drives.

### **Features:**  
- **High-Speed Operation:** Optimized for fast switching applications.  
- **Adjustable Dead-Time Control:** Prevents shoot-through in half-bridge and full-bridge topologies.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Current Limiting:** Protects against overcurrent conditions.  
- **Synchronous Operation:** Allows multiple ICs to be synchronized.  
- **Double-Pulse Suppression:** Prevents multiple pulses in a single cycle.  
- **Totem-Pole Outputs:** Capable of driving power MOSFETs and IGBTs directly.  

The UC3825 is available in multiple package options, including SOIC-16 and PDIP-16.
