Description and Introduction

1MHz Off-Line Current Mode PWM and DC/DC Converter The LT1246CS8 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  
- **Current Sense Threshold:** 1V  
- **Maximum Duty Cycle:** 95%  
- **Package:** SOIC-8  
- **Operating Temperature Range:** 0°C to 70°C  

### **Descriptions:**  
The LT1246CS8 is designed for active power factor correction in AC/DC power supplies. It operates in continuous conduction mode (CCM) and provides high power factor correction with low distortion.  

### **Features:**  
- **Average Current Mode Control** for low distortion  
- **Programmable Oscillator Frequency**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Low Start-Up Current**  
- **Zero Current Detection**  
- **Soft-Start Function**  

This IC is commonly used in power supply designs requiring compliance with power factor correction standards.
