The ON Semiconductor NCP1653DR2 is a highly integrated and advanced Active Power Factor Controller (PFC) designed for use in a variety of applications that demand high power factor and low Total Harmonic Distortion (THD). This innovative controller is engineered to enhance system efficiency and is particularly suited for use in switched-mode power supplies (SMPS), such as those found in televisions, monitors, and eco-friendly lighting systems.

Key Features

• Continuous Conduction Mode (CCM) Operation: The NCP1653DR2 operates in CCM, which ensures efficient power conversion for high power applications while maintaining a stable operation.
• High Power Factor: It is designed to achieve near-unity power factor, which minimizes the reactive power in the electrical system, leading to improved energy efficiency.
• Low THD: The controller significantly reduces Total Harmonic Distortion, ensuring compliance with international power quality standards and reducing stress on the electrical network.
• Frequency Foldback: This feature helps in maintaining high efficiency across a wide range of loads by reducing the switching frequency at light loads.
• Integrated Protections: The NCP1653DR2 includes a suite of protection features such as over-voltage, under-voltage, over-current, and over-temperature protections, ensuring robust and reliable operation.

Applications

• AC-DC Adapters for Laptops and PCs
• Power Supplies for TVs and Monitors
• Energy-efficient Lighting Systems
• High Power AC-DC Converters
