PFS727EG

Overview

The PFS727EG is a high-power Power Factor Correction (PFC) controller from the HiperPFS family, manufactured by Power Integrations. It integrates a high-voltage MOSFET with a continuous conduction mode (CCM) controller in an eSIP-7G package. The device operates within a switching frequency range of 24 kHz to 95 kHz and supports an operating temperature range from -40°C to +150°C. This integration eliminates the need for external current sense resistors, thereby reducing power loss and component count.

Feature Summary

• Integrates a high-voltage MOSFET with a CCM PFC controller to simplify design
• Eliminates the requirement for external current sense resistors
• Reduces associated power losses from sensing components
• Operates across a wide temperature range suitable for industrial environments

Applications

• Appliances
• Computers & Servers

Procurement Notes

Verify availability status as this specific part number may be discontinued or subject to limited supply. Confirm the exact package variant and voltage rating against your schematic requirements. Ensure compliance with RoHS directives if required for your region. Check for obsolescence notices from Power Integrations before finalizing procurement plans.

Selection Notes

Select this component for designs requiring integrated PFC solutions that minimize external passive components. It is suitable for applications where space constraints and efficiency are critical. Consider the thermal performance of the eSIP-7G package in your layout. Verify input voltage ranges and power levels match the device's capabilities.

Part Context

The PFS727EG belongs to the HiperPFS family of high-power PFC controllers. These devices are designed for offline power supplies ranging from 75 W to 400 W. The family utilizes SIP or SMD packages with thermal dissipation through metal tabs or PCB copper. This series focuses on high efficiency and reduced bill of materials through high integration.

Replacement Considerations

Check Power Integrations' official documentation for direct replacements or updated series such as HiperPFS-3 or HiperPFS-4. Verify pin compatibility and electrical specifications before substituting. Consult distributor databases for current availability of alternative part numbers.
