Description and Introduction

1 The UC282T-3 is a high-speed PWM controller manufactured by Texas Instruments (formerly Unitrode). Here are its key specifications, descriptions, and features:  

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

### **Descriptions:**  
- Designed for high-frequency switching power supplies.  
- Features push-pull outputs for driving power MOSFETs or IGBTs.  
- Includes an onboard error amplifier, oscillator, and PWM comparator.  
- Suitable for voltage-mode and current-mode control applications.  

### **Features:**  
- **High-Speed Operation:** Optimized for fast transient response.  
- **Adjustable Dead-Time Control:** Prevents shoot-through in half-bridge or full-bridge configurations.
