PFS706EG

Overview

The PFS706EG is a high-power Power Factor Correction (PFC) controller from the HiperPFS family, manufactured by Power Integrations. It integrates a high-voltage MOSFET and operates in Continuous Conduction Mode (CCM). The device functions at a switching frequency of 95 kHz and utilizes an ESIP-7G package. A key characteristic of this component is its ability to eliminate the need for external current sense resistors, thereby reducing power loss associated with such components.

Feature Summary

• Integrates a high-voltage MOSFET within a single controller package
• Eliminates the requirement for external current sense resistors
• Reduces power loss typically associated with discrete sensing components

Applications

• High power factor correction stages in AC-DC converters
• Power supplies requiring continuous conduction mode operation
• Applications prioritizing efficiency through reduced passive component count

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and temperature range are selected. Confirm that the application design accounts for the integrated high-voltage MOSFET specifications. Ensure compatibility with the intended input voltage range and thermal management requirements for the ESIP-7G package before finalizing procurement.

Selection Notes

Select this component when designing high-power PFC circuits that benefit from simplified topology. The integration of the MOSFET and control logic reduces bill-of-materials complexity. Consider the 95 kHz operating frequency for electromagnetic interference planning. Evaluate the thermal performance needs given the power dissipation characteristics of the integrated switch.
