Power Integrations, Inc. PFC (Power Factor Correction) PFS7628L

The PFS7628L from Quarktwin Technology Ltd. is a Power Factor Correction (PFC) controller designed for high efficiency and power factor across a wide load range. It features a continuous conduction mode (CCM) boost PFC controller integrated with a 600 V MOSFET, allowing for a compact design that eliminates the need for external current sense resistors. The device achieves over 95% efficiency from 10% to 100% load and maintains a power factor greater than 0.95 at 20% load. This product is suitable for various applications, including PCs, high-power adaptors, industrial appliances, and LED lighting. It 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 PFS7628L can handle input voltages up to 305 VAC steady-state and 410 VAC under abnormal conditions, making it robust for diverse operating environments. Its design simplifies compliance with energy efficiency standards, making it a viable option for engineers seeking reliable PFC solutions.
