Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC3802D is a high-performance current-mode PWM controller manufactured by Texas Instruments.  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Operating Frequency:** Up to 1MHz  
- **Supply Voltage (VCC):** 10V to 20V (recommended)  
- **Start-up Voltage:** 8.4V (typical)  
- **Under-Voltage Lockout (UVLO):** 7.6V (turn-off)  
- **Maximum Duty Cycle:** 50% (fixed)  
- **Output Drive Current:** ±1A (peak)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC3802D is designed for high-frequency power supply applications, providing precise control with current-mode operation. It includes features like soft-start, cycle-by-cycle current limiting, and under-voltage lockout for robust performance.  

### **Features:**  
- **Current-Mode Control:** Improves transient response and simplifies loop compensation.  
- **50% Duty Cycle Limitation:** Ensures transformer reset in forward converters.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Low Startup Current:** Enables efficient power-up.  
- **High-Speed Operation:** Suitable for high-frequency switching applications.  

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