PFS724EG

Overview

The PFS724EG is a discontinued Power Factor Correction (PFC) controller from the HiperPFS family by Power Integrations. It integrates a 600 V power MOSFET and diode in a single low-profile eSIP-7 package. The device supports a maximum output power of 120 W at 90 VAC input. It operates within a switching frequency range of 24 kHz to 95 kHz. The component is designed for through-hole mounting and functions within a minimum operating temperature of -40°C.

Feature Summary

• Integrates a 600 V power MOSFET and diode in a single low-profile package
• Optimized for high power factor and efficiency across the entire load range
• Eliminates external current sense resistors using innovative control techniques
• Features wide bandwidth spread spectrum effect to minimize EMI filtering requirements

Applications

• Power factor correction stages in offline power supplies
• Adapters and chargers requiring high efficiency at light loads
• Consumer electronics power systems
• Industrial equipment power supplies

Procurement Notes

The PFS724EG is officially listed as an End-of-Life (EOL) product by Power Integrations. Availability is restricted, and it may not be sold in all regions by distributors such as Mouser. Engineers should verify current stock status with authorized suppliers and consider design-in alternatives due to discontinuation. Verify RoHS compliance details directly with the manufacturer or distributor before procurement.

Selection Notes

Select this component for designs requiring integrated PFC and power MOSFET functionality in a compact eSIP-7 package. It is suitable for applications needing up to 120 W output power with 90 VAC input. The device offers cycle-by-cycle current limit and Safe Operating Area protection. Ensure the design accommodates the specified switching frequency range and thermal requirements for through-hole mounting.

Part Context

The PFS724EG belongs to the HiperPFS family of controllers, which combine CCM boost PFC control, gate driver, and power MOSFETs. This family targets mid-power offline converters, optimizing performance across varying load conditions. The integration reduces component count and board space compared to discrete solutions, supporting efficient power conversion in standard AC-DC applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the PFS724EG is discontinued, engineers must evaluate newer generations such as the HiperPFS-4 or HiperPFS-5 series for replacement. These newer devices offer updated features and availability. Consult official manufacturer resources for pin-compatible or functionally equivalent alternatives.
