Description and Introduction

HIGH VOLTAGE OFF-LINE SWITCHING REGULATOR The MC33363AP is a high-voltage switching regulator manufactured by ON Semiconductor. It is designed for offline power supply applications and operates as a current-mode controller.  

### **Specifications:**  
- **Input Voltage Range:** Up to 450V  
- **Output Voltage:** Adjustable  
- **Switching Frequency:** Up to 100kHz  
- **Current Sensing:** Internal current sense resistor  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The MC33363AP is optimized for flyback and forward converter topologies.  
- It includes features like soft-start, cycle-by-cycle current limiting, and undervoltage lockout (UVLO).  
- The device is suitable for AC/DC power supplies, battery chargers, and auxiliary power supplies.  

### **Features:**  
- **High-Voltage Startup Circuit:** Reduces external component count.  
- **Current-Mode Control:** Improves transient response and simplifies loop compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Internal Overcurrent Protection:** Enhances system reliability.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

HIGH VOLTAGE OFF-LINE SWITCHING REGULATOR

Alternative Part Number

  • UC3842AN --: Industry-standard current-mode PWM controller in a DIP-8 package, widely used as a functional substitute for offline flyback controller ICs like the MC33363A.
  • NCP1200P60 --: High-voltage offline PWM controller in DIP-8 with integrated startup current source, closely matching the application role of the MC33363A in SMPS designs.
  • SG6841DZ --: Green-mode PWM controller for offline flyback converters in DIP-8, offering comparable control functionality and a different series naming for easy distinction.
