Description and Introduction

BiCMOS Power Factor Preregulator The UCC2818DWTRG4 is a high-performance, current-mode PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** UCC2818DWTRG4  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range:** 10.5V to 17V (operating), 20V (max)  
- **Output Frequency:** Adjustable up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Switching Frequency:** Programmable via external resistor and capacitor

- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-16 (DW)  

### **Descriptions:**  
The UCC2818DWTRG4 is a versatile PWM controller designed for high-efficiency power supply applications. It features current-mode control for improved transient response and loop stability. The device includes protections such as undervoltage lockout (UVLO), cycle-by-cycle current limiting, and soft-start functionality.  

### **Features:**  
- **Current-Mode Control:** Enhances loop stability and transient response.  
- **Programmable Switching Frequency:** Adjustable via external components.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  
- **SOIC-16 Package:** Compact and suitable for surface-mount applications.  

This information is based solely on the manufacturer's datasheet and technical documentation.
