Description and Introduction

0 The UCC2813DTR-1 is a high-performance, current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 10.8V to 16.5V  
- **Operating Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current:** ±1A (peak)  
- **Switching Frequency:** Adjustable via external components  
- **Package:** SOIC-8 (DTR)  
- **Operating Temperature Range:** -40°C to +105°C  

### **Descriptions:**  
The UCC2813DTR-1 is a versatile PWM controller designed for power supply applications. It features current-mode control for improved transient response and cycle-by-cycle current limiting. It is commonly used in AC/DC converters, power factor correction (PFC) circuits, and DC/DC converters.  

### **Features:**  
- **Current-Mode Control:** Enhances loop stability and transient response.  
- **Programmable Switching Frequency:** Adjustable via external resistor and capacitor.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the input voltage range.  
- **High-Current Totem Pole Output:** Supports fast MOSFET switching.  
- **Leading Edge Blanking:** Improves noise immunity in current sensing.  

This information is sourced from TI's official documentation. For detailed application notes, refer to the datasheet.
