Description and Introduction

SMPS Controller The part KA3882ED is manufactured by FAIRCHILD (Fairchild Semiconductor). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** FAIRCHILD (Fairchild Semiconductor)  
- **Part Number:** KA3882ED  
- **Category:** Integrated Circuit (IC)  
- **Type:** PWM (Pulse Width Modulation) Controller  
- **Package:** SOP-8 (Small Outline Package, 8-pin)  

### **Descriptions:**  
The KA3882ED is a fixed-frequency current-mode PWM controller IC designed for power supply applications. It is commonly used in switch-mode power supplies (SMPS) and DC-DC converters. The device provides precise control over the output voltage and current, ensuring stable and efficient power conversion.  

### **Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Fixed Operating Frequency:** Typically 52 kHz (may vary based on external components).  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within specified voltage ranges.  
- **High-Current Totem Pole Output:** Suitable for driving power MOSFETs.  
- **Low Start-Up Current:** Reduces power consumption during initial operation.  
- **Soft-Start Function:** Prevents excessive inrush current during startup.  
- **Error Amplifier:** Provides feedback regulation for stable output.  
- **Overcurrent Protection:** Safeguards against excessive current conditions.  

This information is strictly based on available data for the KA3882ED from FAIRCHILD.
