Description and Introduction

1 The UCC3809N-2 is a high-performance current-mode PWM controller manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

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

### **Part Number:**  
UCC3809N-2  

### **Description:**  
The UCC3809N-2 is a BiCMOS current-mode PWM controller designed for high-frequency power supply applications. It provides precise control for switching power supplies with features like adjustable switching frequency, soft-start, and cycle-by-cycle current limiting.  

### **Key Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Adjustable Switching Frequency:** Up to 1 MHz operation.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Low Startup and Operating Current:** Improves efficiency.  
- **BiCMOS Technology:** Combines high-speed bipolar and low-power CMOS.  
- **Wide Supply Voltage Range:** Typically 8V to 17V.  
- **Totem-Pole Output:** Capable of driving power MOSFETs directly.  

### **Applications:**  
- Switch-mode power supplies (SMPS)  
- DC-DC converters  
- Power factor correction (PFC) circuits  
- Isolated and non-isolated power supplies  

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