Power Integrations, Inc. PFC (Power Factor Correction) PFS725EG

The PFS725EG from Quarktwin Technology Ltd. is a high-power PFC controller designed for applications requiring efficient power factor correction. It integrates a high-voltage MOSFET, controller, and gate driver in a compact eSIP-7G package, capable of delivering up to 435 W of continuous output power and 480 W peak output power. This device is compliant with EN61000-3-2 Class D standards, ensuring it meets stringent electromagnetic interference requirements. The PFS725EG features high efficiency, exceeding 95% from 10% load to full load, and offers low no-load consumption of less than 130 mW at 230 VAC. It employs a variable-frequency continuous conduction mode (VF-CCM) to optimize efficiency across varying loads and input voltages, while also minimizing EMI filtering needs. Protection features include undervoltage, overvoltage, thermal shutdown, and cycle-by-cycle current limiting, which enhance reliability and reduce the need for external components. This product is suitable for a range of applications, including high-power adapters, LED lighting, and industrial equipment, making it a versatile choice for engineers looking to implement effective power factor correction in their designs.
