Description and Introduction

High Speed Current Mode Pulse Width Modulators The LT1242IS8#PBF is a power factor correction (PFC) controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Linear Technology (Analog Devices)  
- **Package:** SOIC-8  
- **Type:** Power Factor Correction (PFC) Controller  
- **Input Voltage Range:** Up to 275V AC  
- **Switching Frequency:** Adjustable (typically up to 200kHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:**  
  - Average current mode control  
  - Low harmonic distortion  
  - Programmable switching frequency  
  - Soft-start capability  
  - Overvoltage protection  
  - Under-voltage lockout (UVLO)  

### **Description:**  
The LT1242IS8#PBF is designed for high-performance power factor correction applications. It uses average current mode control to achieve low input current distortion and high power factor. It is suitable for boost-type PFC circuits in AC/DC power supplies.  

### **Features:**  
- **Average Current Mode Control:** Ensures low harmonic distortion.  
- **Programmable Frequency:** Allows optimization of efficiency and component size.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Protection Features:** Includes overvoltage protection and under-voltage lockout.  
- **Wide Input Voltage Range:** Supports universal AC line inputs.  

This IC is commonly used in power supply designs requiring compliance with power quality standards such as IEC 61000-3-2.  

(Note: Always refer to the official datasheet for detailed specifications and application guidelines.)
