Description and Introduction

High Voltage GreenLine Power Factor Controller The MC33368DR2 is a high-voltage power factor correction (PFC) controller manufactured by ON Semiconductor. Below are the key specifications, descriptions, and features based on available factual information:

### **Manufacturer:**  
- **ON Semiconductor**  

### **Specifications:**  
- **Type:** High-Voltage PFC Controller  
- **Package:** SOIC-8  
- **Input Voltage Range:** Up to 450V  
- **Operating Frequency:** Adjustable (typically up to 250 kHz)  
- **Output Drive:** Totem Pole (for driving external MOSFET)  
- **Control Method:** Average Current Mode Control  
- **Power Factor Correction:** >0.99  
- **Startup Current:** Low (typically <100 µA)  
- **Protection Features:**  
  - Overvoltage Protection (OVP)  
  - Undervoltage Lockout (UVLO)  
  - Open-Loop Protection  

### **Descriptions:**  
The MC33368DR2 is designed for power factor correction in AC-DC power supplies, improving efficiency and compliance with regulatory standards. It operates in continuous conduction mode (CCM) and provides precise current shaping for near-unity power factor.  

### **Features:**  
- **Average Current Mode Control:** Ensures low distortion and high power factor.  
- **Low Startup Current:** Reduces power consumption during startup.  
- **Programmable Operating Frequency:** Allows optimization for efficiency and EMI.  
- **Internal Voltage Reference:** Provides stable regulation.  
- **Zero Current Detection (ZCD):** Ensures proper switching transitions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **RoHS Compliant:** Meets environmental standards.

Description and Introduction

High Voltage GreenLine Power Factor Controller The MC33368DR2 is a power factor correction (PFC) controller manufactured by Motorola (now ON Semiconductor). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Motorola (ON Semiconductor)  
- **Part Number:** MC33368DR2  
- **Type:** High Voltage PFC Controller  
- **Package:** SOIC-8  
- **Operating Voltage Range:** 10V to 16V (typical)  
- **Start-Up Voltage:** 10.5V (typical)  
- **UVLO (Undervoltage Lockout):** 9V (turn-off), 10.5V (turn-on)

### **Descriptions:**  
The MC33368DR2 is a high-performance PFC controller designed for power supplies requiring power factor correction. It operates in critical conduction mode (CRM) to improve efficiency and reduce EMI. The device features a high-voltage startup circuit, eliminating the need for an external bias supply.  

### **Features:**  
- **Critical Conduction Mode (CRM) Operation**  
- **Internal High-Voltage Startup Circuit**  
- **Low Distortion, High Power Factor (>0.99 achievable)**  
- **Programmable Switching Frequency**  
- **Overvoltage Protection (OVP)**  
- **Undervoltage Lockout (UVLO)**  
- **Peak Current Limiting**  
- **Low Startup and Operating Current**  
- **SOIC-8 Package for Compact Designs**
