PFS7325H

Overview

The PFS7325H is a high-power Power Factor Correction (PFC) controller from Power Integrations, featuring an integrated high-voltage MOSFET and Qspeed technology. It supports continuous conduction mode (CCM) operation with a maximum input voltage of 265 V AC and a maximum output voltage of 385 V DC. The device operates within an input voltage range of 90 to 265 V AC and provides a current limit of 6.2 A, with a maximum output current capability of 11.3 A. Designed for robust performance, it functions across a temperature range of -40 °C to +150 °C. The component utilizes a 13-pin eSIP package, measuring 16.59 mm in length, 2.06 mm in width, and 8.25 mm in height.

Procurement Notes

Verify the specific suffix letter (e.g., H, L) as it denotes package variations or thermal characteristics. Confirm that the obsolete status does not impact long-term supply chain stability for existing designs. Ensure compatibility with the intended PCB footprint for the eSIP package before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high-efficiency PFC with integrated switching elements. Consider the thermal management requirements associated with the eSIP package and the +150 °C junction temperature rating. Evaluate the 6.2 A current limit against peak load demands to ensure adequate headroom for system reliability and transient response.

Part Context

The PFS7325H belongs to the HiperPFS family of high-power PFC controllers. This series is designed to replace discrete solutions by integrating the controller, driver, and power switch into a single package. It targets applications demanding high power factor and low total harmonic distortion in medium to high-power AC-DC conversion stages.

Replacement Considerations

The PFS7325H is marked as obsolete. The PFS7525H is listed as a similar available substitute. Verify electrical pinout compatibility and thermal performance specifications before transitioning to the replacement part.
