Power Integrations, Inc. Power Factor Correction PFS7724L

The PFC Controller from Power Integrations, specifically the HiperPFS-4 series, is designed for high efficiency and power factor correction across a wide load range. It operates effectively in temperatures from -40 to 150 degrees Celsius and features a built-in 600 V MOSFET, eliminating the need for external current sense resistors. The controller achieves over 95% efficiency from 10% to 100% load and maintains a power factor greater than 0.95 at 20% load. This device incorporates advanced digital techniques for line monitoring and power factor enhancement, while also providing comprehensive protection features such as undervoltage, overvoltage, and thermal shutdown. The HiperPFS-4 is suitable for various applications, including PCs, high-power adapters, industrial equipment, and LED lighting, with maximum continuous output power ratings ranging from 75 W to 405 W. Its compact design simplifies system integration and reduces overall component count, making it a reliable choice for engineers seeking efficient power solutions.
