Description and Introduction

High Speed PWM Controller The UC2823DWTR is a high-speed PWM controller manufactured by UNITRODE. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** UNITRODE (now part of Texas Instruments)  
- **Type:** High-Speed PWM Controller  
- **Package:** SOIC-16 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** Up to 30V  
- **Switching Frequency:** Up to 1MHz  
- **Output Drive Current:** 2A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 10MHz  

### **Descriptions:**  
- The UC2823DWTR is designed for high-frequency switching power supplies.  
- It features a high-speed error amplifier and a precision oscillator for accurate PWM control.  
- Suitable for push-pull, forward, and flyback converter topologies.  
- Includes under-voltage lockout (UVLO) and soft-start functionality.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Adjustable Dead-Time Control:** Prevents shoot-through in half-bridge applications.  
- **Synchronous Operation:** Allows multiple controllers to be synchronized.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Dual Output Drivers:** Capable of driving MOSFETs or IGBTs directly.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Current Limiting:** Protects against overcurrent conditions.  

This information is based on UNITRODE's datasheet for the UC2823DWTR.
