PFS726EG

Overview

The PFS726EG is a Power Factor Correction (PFC) controller from the HiperPFS-3 family by Power Integrations. It integrates a 600 V power MOSFET and operates at a switching frequency of 60 kHz. The device supports an input voltage range of 90 VAC to 265 VAC and delivers up to 105 W of output power. It utilizes a low-profile ESIP package with 16 pins, designed for surface mount installation.

Feature Summary

• Integrates a high-voltage power MOSFET within a single compact package to reduce component count.
• Optimized for high power factor and efficiency across the entire load range.
• Features a low-profile package design suitable for space-constrained applications.

Applications

• Offline power supplies requiring power factor correction
• Adapters and chargers for consumer electronics
• General-purpose AC-DC conversion systems

Procurement Notes

Verify the specific suffix and tape-and-reel quantity requirements directly with the manufacturer or authorized distributors. Confirm that the ESIP package dimensions match your PCB footprint constraints. Ensure compliance with RoHS directives if required for your target market. Check for any recent lifecycle status updates regarding availability.

Selection Notes

Select this component when designing PFC stages for universal input offline applications up to 105 W. The integrated MOSFET simplifies thermal management compared to discrete solutions. Consider the 60 kHz switching frequency for balancing EMI performance and magnetics size. Evaluate the ESIP package profile against enclosure height limitations in your final product design.

Part Context

The PFS726EG belongs to the HiperPFS-3 family, which combines a PFC controller with a 600 V MOSFET. This integration targets mid-power applications where high efficiency and reduced bill-of-materials are critical. The family is known for optimizing performance across wide input voltage ranges without external bias requirements.
