Description and Introduction

High Speed Current Mode Pulse Width Modulators The LT1244CN8 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 300kHz  
- **Output Drive Current:** ±1A (peak)  
- **Power Factor Correction:** >0.99  
- **Total Harmonic Distortion (THD):** <5%  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** 0°C to 70°C  

### **Descriptions:**  
The LT1244CN8 is designed for high-efficiency power factor correction in AC/DC power supplies. It uses average current mode control to achieve near-unity power factor and low harmonic distortion. The IC is suitable for boost, flyback, and buck-boost PFC applications.  

### **Features:**  
- **Average Current Mode Control** for precise PFC  
- **Programmable Oscillator Frequency**  
- **Low Start-Up Current** (<150µA)  
- **Undervoltage Lockout (UVLO)**  
- **Overvoltage Protection (OVP)**  
- **Soft-Start Function**  
- **Zero Current Detection**  
- **Wide Supply Voltage Range**  

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