Description and Introduction

High Speed Current Mode Pulse Width Modulators The LT1241IN8 is a power factor correction (PFC) controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Operating Frequency:** Up to 500kHz  
- **Output Drive Current:** ±500mA  
- **Power Factor Correction:** Yes  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LT1241IN8 is designed for high-performance power factor correction in AC/DC power supplies. It operates in continuous conduction mode (CCM) and provides a stable output voltage while maintaining near-unity power factor.  

### **Features:**  
- **Average Current Mode Control:** Ensures low harmonic distortion.  
- **Precision Reference:** 2.5V ±1% for accurate regulation.  
- **Low Start-Up Current:** 150µA typical.  
- **Overvoltage Protection:** Prevents damage due to excessive output voltage.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Zero Current Detection:** Improves efficiency at light loads.  

This IC is commonly used in switch-mode power supplies (SMPS), LED drivers, and industrial power systems.  

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

Description and Introduction

High Speed Current Mode Pulse Width Modulators The LT1241IN8 is a power factor correction (PFC) controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Operating Frequency:** Up to 300kHz  
- **Maximum Duty Cycle:** 95%  
- **Quiescent Current:** 2.5mA (typical)  
- **Output Drive Current:** ±500mA  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LT1241IN8 is designed for high-efficiency power factor correction in AC/DC power supplies. It uses average current mode control to ensure low harmonic distortion and high power factor. The IC includes features like soft-start, overvoltage protection, and a precision reference for accurate regulation.  

### **Features:**  
- **Average Current Mode Control** for low distortion  
- **Programmable Operating Frequency**  
- **Soft-Start Function** for controlled startup  
- **Overvoltage Protection (OVP)**  
- **Precision 2.5V Reference**  
- **Low Start-Up Current**  
- **High Noise Immunity**  

This IC is commonly used in power supplies, LED drivers, and industrial applications requiring power factor correction.  

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