Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC3800N is a high-performance current-mode PWM controller manufactured by UNITRODE.  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Operating Frequency:** Up to 1MHz  
- **Supply Voltage (VCC):** 10V to 20V  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Start-up Current:** 0.5mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin DIP (PDIP)  

### **Descriptions:**  
The UCC3800N is designed for high-frequency switching power supplies, offering precise control with current-mode operation. It features built-in protections such as under-voltage lockout (UVLO) and cycle-by-cycle current limiting.  

### **Features:**  
- **Current-Mode Control:** Provides inherent line and load regulation.  
- **High-Frequency Operation:** Supports switching frequencies up to 1MHz.  
- **Low Start-up Current:** Ensures efficient power-up.  
- **Under-Voltage Lockout (UVLO):** Prevents operation below safe voltage levels.  
- **Cycle-by-Cycle Current Limiting:** Enhances system reliability.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Wide Duty Cycle Range:** Allows flexible power supply design.  

This information is based on UNITRODE's official documentation for the UCC3800N.
