Description and Introduction

High Speed PWM Controller The UC2813 is a high-speed PWM controller manufactured by Texas Instruments. Below are the key specifications, descriptions, and features based on UN standards and manufacturer details:

### **Manufacturer:**  
- **Texas Instruments**  

### **UN Specifications:**  
- **Part Number:** UC2813  
- **Type:** High-Speed PWM Controller  
- **Package Options:** SOIC-16, PDIP-16  

### **Descriptions:**  
- A fixed-frequency pulse-width modulation (PWM) controller optimized for high-speed applications.  
- Designed for switching power supplies and DC-DC converters.  
- Operates at high switching frequencies, making it suitable for compact power supply designs.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to **1 MHz**.  
- **Precision Reference:** Internal **5.1V ±1%** bandgap voltage reference.  
- **Dual Outputs:** Push-pull outputs capable of sourcing/sinking **1A peak current**.  
- **Adjustable Dead-Time Control:** Allows optimization of power efficiency.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Error Amplifier:** High-gain bandwidth for improved loop response.  
- **Synchronization Capability:** Can be synchronized to an external clock.  

This information is based on the manufacturer's datasheet and UN-recognized specifications.
