Power Integrations, Inc. PFC (Power Factor Correction) PFS7326H

The PFS7326H is a high-power Power Factor Correction (PFC) controller from the HiperPFS-2 family, designed for applications requiring efficient power management. It integrates a continuous conduction mode (CCM) boost PFC controller, a high-voltage MOSFET, and an ultra-low reverse recovery loss Qspeed diode within a compact eSIP-16D package. This device supports a maximum continuous output power of 230 W at 90 VAC and can deliver up to 260 W in full mode. Key features include high efficiency exceeding 95% across a wide load range, low no-load consumption of less than 200 mW at 230 VAC, and a power factor greater than 0.95 at 50% load. The PFS7326H also incorporates advanced protection mechanisms such as undervoltage (UV), overvoltage (OV), and thermal shutdown, along with a programmable power good signal and user-selectable power limit functionality. The device is compliant with EN61000-3-2 Class C and D standards, making it suitable for high-efficiency designs, including PCs, high-power adapters, and industrial applications. Its innovative design reduces component count and simplifies thermal management, making it a reliable choice for engineers looking to optimize power factor and efficiency in their projects.
