Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC3802N is a high-performance current-mode PWM controller manufactured by Texas Instruments.  

### **Specifications:**  
- **Input Voltage Range (VCC):** 8.5V to 12V (operating), 12V (max)  
- **Output Drive Current:** ±1A (peak)  
- **Switching Frequency Range:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The UCC3802N is designed for offline and DC-DC power supply applications. It provides precise control for switching power supplies with features like under-voltage lockout (UVLO), cycle-by-cycle current limiting, and soft-start capability.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **High-Current Totem-Pole Output:** Directly drives power MOSFETs.  
- **Internal Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **Low Startup Current:** Reduces power consumption during startup.  

The UCC3802N is commonly used in AC/DC converters, DC/DC converters, and power supply modules.
