Description and Introduction

0 The UCC2813D-4 is a high-performance, BiCMOS, average-mode current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Manufacturer:**  
- **Texas Instruments (TI)**  

### **Specifications:**  
- **Control Method:** Average Current-Mode PWM  
- **Topology:** Supports Boost, Flyback, Forward, and other topologies  
- **Operating Frequency:** Up to 1MHz  
- **Input Voltage Range (VDD):** 10V to 17V (start-up), 7.5V to 17V (operating)  
- **Output Drive Current:** ±1.5A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5MHz  
- **Current Sense Input Range:** ±1V  
- **Shutdown Current:** <100µA  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-14  

### **Descriptions:**  
- Designed for power factor correction (PFC) applications  
- Features high-speed PWM control for efficient power conversion  
- Includes an onboard oscillator, error amplifier, and current-sensing comparator  
- Provides precise average current control for improved line and load regulation  

### **Features:**  
- **BiCMOS Technology:** Low power consumption and high-speed operation  
- **Programmable Oscillator:** Allows frequency adjustment with external components  
- **Soft-Start Function:** Reduces inrush current during startup  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits  
- **Peak Current Limiting:** Protects against overcurrent conditions  
- **Leading Edge Blanking:** Improves noise immunity in current sensing  

This controller is commonly used in AC/DC power supplies, LED drivers, and industrial power systems.
