Description and Introduction

BiCMOS Power Factor Preregulator 16-PDIP -40 to 85 The UCC2818ANG4 is a high-performance, current-mode PWM controller manufactured by Texas Instruments (TEXAS). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TEXAS)  
- **Part Number:** UCC2818ANG4  
- **Type:** Current-Mode PWM Controller  
- **Package:** PDIP-8 (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** Up to 17V  
- **Output Voltage:** Adjustable via external components  
- **Switching Frequency:** Up to 1MHz (programmable)  
- **Duty Cycle Range:** 0% to 100%  
- **Peak Output Current:** 1A (source/sink)  

### **Descriptions:**
- The UCC2818ANG4 is designed for high-efficiency power supply applications, including offline and DC-DC converters.  
- It features current-mode control for improved loop response and simplified compensation.  
- Includes built-in protections such as undervoltage lockout (UVLO), cycle-by-cycle current limiting, and soft-start capability.  

### **Features:**
- **Current-Mode Control:** Enhances transient response and simplifies feedback loop design.  
- **Programmable Switching Frequency:** Allows flexibility in design optimization.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Low Startup Current:** Reduces power consumption during initial operation.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  

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