Description and Introduction

0 The UCC2813PW-2 is a high-performance, BiCMOS, current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range (VCC):** 8.5V to 17V  
- **Operating Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current (Source/Sink):** 1A (Peak)  
- **Error Amplifier Bandwidth:** 5MHz  
- **Soft-Start Capability:** Yes  
- **UVLO (Undervoltage Lockout):** 8V (Typical)  
- **Package:** 16-pin TSSOP (PW)  

### **Descriptions:**  
The UCC2813PW-2 is designed for high-frequency switching power supplies, offering precise current-mode control with fast response. It includes features like soft-start, cycle-by-cycle current limiting, and undervoltage lockout for robust operation in power conversion applications.  

### **Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Programmable Oscillator:** Allows flexible frequency adjustment.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Low Startup Current:** Typically 0.5mA.  
- **High-Speed Error Amplifier:** Ensures tight regulation.  
- **BiCMOS Technology:** Provides low power consumption and high-speed operation.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  

This device is commonly used in AC/DC converters, power factor correction (PFC) circuits, and offline power supplies.
