Description and Introduction

Power Factor Controllers The MC33262DR2G is a power factor controller IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Input Voltage Range:** 10.5V to 16V (VCC)  
- **Operating Frequency:** Adjustable (typically up to 250 kHz)  
- **Start-Up Current:** 150 µA (typical)  
- **Quiescent Current:** 4 mA (typical)  
- **Output Drive Current:** ±500 mA (peak)  
- **Multiplier Input Voltage Range:** 0V to 4.5V  
- **Error Amplifier Input Voltage Range:** 0V to 5V  
- **Error Amplifier Gain Bandwidth:** 1 MHz (typical)  
- **Package:** SOIC-8  

### **Descriptions:**  
The MC33262DR2G is a high-performance power factor correction (PFC) controller designed for boost converter topologies. It operates in critical conduction mode (CRM) to achieve near-unity power factor and low harmonic distortion. The IC features an internal start-up timer, zero-current detection, and an integrated multiplier for accurate current shaping.  

### **Features:**  
- **Power Factor Correction (PFC) Controller**  
- **Critical Conduction Mode (CRM) Operation**  
- **Internal Start-Up Timer**  
- **Zero-Current Detection**  
- **Precision Reference Voltage (2.5V ±1%)**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Low Standby Power Consumption**  
- **SOIC-8 Package for Compact Design**  

This IC is commonly used in AC-DC power supplies, LED drivers, and other applications requiring high power factor and efficiency.
