Description and Introduction

Fairchild Power Switch(FPS) The part **KA5S0965** is a **Switching Regulator IC** manufactured by **FAIRCHILD**. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** FAIRCHILD  
- **Type:** Switching Regulator IC  
- **Topology:** Flyback Converter  
- **Input Voltage Range:** 85V to 265V AC (for universal line operation)  
- **Output Power:** Up to 65W (typical)  
- **Switching Frequency:** 100kHz (fixed)  
- **Output Voltage:** Adjustable (depends on external components)  
- **Current Limit Protection:** Yes  
- **Overvoltage Protection (OVP):** Yes  
- **Thermal Shutdown Protection:** Yes  
- **Package Type:** TO-220F (isolated type)  

### **Descriptions:**  
The **KA5S0965** is a **high-voltage power switch IC** designed for **offline flyback converter** applications. It integrates a **high-voltage MOSFET** and **PWM controller**, making it suitable for **AC/DC power supplies** in consumer electronics, such as TVs, monitors, and adapters.  

### **Features:**  
- **Built-in high-voltage MOSFET** (650V, 5A)  
- **Low standby power consumption**  
- **Fixed 100kHz switching frequency**  
- **Soft-start function** (reduces inrush current)  
- **Cycle-by-cycle current limiting**  
- **Auto-restart protection** for fault conditions  
- **Isolated TO-220F package** for better thermal performance  

This information is strictly based on the available knowledge base. Let me know if you need further details.
