Description and Introduction

Power Factor Controllers The MC33262DG is a power factor controller (PFC) IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Input Voltage Range:** 8.5V to 18V  
- **Operating Frequency:** Up to 250kHz  
- **Start-Up Current:** 150µA (typical)  
- **Quiescent Current:** 4mA (typical)  
- **Output Drive Current:** ±500mA (peak)  
- **Error Amplifier Bandwidth:** 1MHz  
- **Multiplier Bandwidth:** 1MHz  
- **ZCD Input Threshold:** 1.4V (typical)  
- **Package:** SOIC-8  

### **Descriptions:**  
The MC33262DG is a monolithic IC designed for power factor correction in AC/DC power supplies. It operates in transition mode (boundary conduction mode) to improve efficiency and reduce switching losses. The IC includes features like an internal start-up timer, zero-current detection (ZCD), and a transconductance error amplifier for precise control.  

### **Features:**  
- **Power Factor Correction (PFC) Controller**  
- **Transition Mode Operation**  
- **Internal Start-Up Timer**  
- **Zero-Current Detection (ZCD)**  
- **Low Distortion, High Power Factor**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Transconductance Error Amplifier**  
- **Multiplier for Input Current Shaping**  

This IC is commonly used in switch-mode power supplies (SMPS), LED drivers, and other applications requiring high power factor correction.
