PFS704EG

Overview

The PFS704EG is a discontinued Power Factor Correction (PFC) controller from the HiperPFS family by Power Integrations. It integrates a continuous conduction mode (CCM) boost PFC controller, gate driver, and high-voltage power MOSFET into a single low-profile eSIP™ power package. The device operates with a switching frequency range of 24 kHz to 95 kHz. It is designed for applications requiring high efficiency and power factor correction without external current sense resistors.

Feature Summary

• Integrates CCM boost PFC controller, gate driver, and high-voltage power MOSFET in a compact eSIP package
• Eliminates external current sense resistors to reduce power loss and component count
• Utilizes innovative control techniques to adjust switching frequency based on load and line conditions
• Includes comprehensive protection features such as soft-start, UV/OV, brown-in/out, and thermal shutdown

Applications

• PC power supplies
• High-power adapters
• Printers
• High-power LED lighting
• LCD TVs and video game consoles

Procurement Notes

Verify availability status carefully as this component is listed as discontinued. Confirm that any available stock represents genuine original manufacturer parts. Check for obsolescence notices or end-of-life notifications from Power Integrations before finalizing procurement plans to ensure long-term supply chain stability.

Selection Notes

Consider the integrated nature of the PFS704EG for designs prioritizing board space reduction and simplified BOMs. Evaluate its suitability for applications requiring high efficiency across varying load ranges. Assess if the specific eSIP package constraints meet the thermal and mechanical requirements of the target enclosure design compared to discrete solutions.

Part Context

The PFS704EG belongs to the HiperPFS series, which combines PFC and power switching functions. This integration approach aims to simplify power supply design by reducing the number of external components required. The series targets universal input AC-DC conversion needs in consumer and industrial electronics.
