ON Semiconductor MC33364DR2 High Voltage GreenLine SMPS Controller

The MC33364DR2 from ON Semiconductor is a cutting-edge, highly efficient, off-line switch mode power supply (SMPS) controller designed for high-voltage applications. This GreenLine™ controller is optimized to deliver performance with reduced power consumption, making it an ideal choice for energy-sensitive electronics.

Key Features

• High-Voltage Startup: The MC33364DR2 is equipped with a high-voltage startup circuit, enabling it to handle input voltages up to 600V, which is particularly useful for fluctuating power grid conditions.
• Low Standby Power: With its focus on energy efficiency, this controller ensures that standby power is kept to a minimum, contributing to the overall reduction of power usage in standby mode.
• Frequency Jittering: The built-in frequency jittering capability helps in reducing electromagnetic interference (EMI), thus simplifying compliance with EMI regulations and improving the reliability of the end application.
• Internal Over-Temperature Protection: Safety is a paramount concern in power management, and the MC33364DR2 includes an internal thermal shutdown feature to protect against overheating.
• Undervoltage Lockout (UVLO): This feature ensures that the device operates only when the input voltage is within an acceptable range, preventing damage from low voltage conditions.

Applications

This versatile controller is particularly suited for high-performance applications where efficiency and reliability are critical. It is commonly used in:

• Power supplies for consumer electronics
• Power adapters and chargers
• Standby and auxiliary power supplies
• Industrial power systems

Technical Specifications

The MC33364DR2 is available in an 8-pin SOIC package and is characterized for operation from -40°C to +105°C. It operates with a switching frequency of 60 kHz, which strikes a balance between efficiency and component size, allowing for compact power supply designs.
