Description and Introduction

1 The UCC3808AN-2 is a PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Current-Mode PWM Controller  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Operating Frequency:** Up to 1MHz  
- **Supply Voltage (VCC):** 10V to 20V  
- **Output Current (Source/Sink):** 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 PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The UCC3808AN-2 is a high-performance current-mode PWM controller designed for offline and DC-DC power supplies. It features low start-up and operating currents, making it suitable for energy-efficient applications. The device includes an internal oscillator, error amplifier, current sensing comparator, and totem-pole output driver.  

### **Features:**  
- **Current-Mode Control:** Provides improved loop response and simplified compensation.  
- **Programmable Oscillator:** Allows frequency adjustment via external components.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the specified voltage range.  
- **Soft-Start Capability:** Reduces inrush current during start-up.  
- **Internal Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **High-Current Totem-Pole Output:** Directly drives power MOSFETs.  
- **Low Power Consumption:** Optimized for efficiency.  

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