ON Semiconductor NCP1653DR2G Power Factor Controller

The ON Semiconductor NCP1653DR2G is a sophisticated power factor controller designed for use in compact and efficient power conversion applications. This integrated circuit is tailored to enhance the power factor of electronic systems by optimizing the phase angle between the input voltage and current, thereby reducing reactive power and improving the overall efficiency of the power supply.

With its advanced features, the NCP1653DR2G is particularly suitable for use in switched-mode power supplies (SMPS), including those found in consumer electronics, office equipment, and industrial machinery. Its applications range from AC-DC adapters and power supplies for LCD TVs to power supplies for desktop computers and servers.

This controller operates in Continuous Conduction Mode (CCM), which makes it ideal for higher power applications that require a stable and continuous flow of energy. The NCP1653DR2G is designed to work with a wide range of universal AC input voltages, from 85 VAC to 265 VAC, accommodating global power standards and making it versatile for international products.

The device features a built-in high-voltage startup circuit, which ensures reliable startup and reduces external component count, thus simplifying the design and reducing overall system cost. Additionally, its integrated protections, such as overvoltage, undervoltage, and overcurrent protections, safeguard the system against a variety of electrical anomalies and ensure long-term reliability.

ON Semiconductor's NCP1653DR2G comes in a compact SOIC-8 package, which is not only space-saving but also conducive to creating high-density power supply designs. The small footprint allows designers to create more compact power solutions without compromising performance.

In summary, the NCP1653DR2G offers a balance of efficiency, versatility, and protection, making it an excellent choice for designers looking to create high-performance power supplies with improved power factor and reduced energy consumption.
