PFS7523L

Overview

The PFS7523L is a HiperPFS-3 series power factor correction controller designed for continuous conduction mode (CCM) boost PFC applications. It supports peak output powers up to 120 W with input voltages ranging from 90 VAC to 264 VAC. The device utilizes an eSIP-16G package and incorporates comprehensive protection features including output undervoltage, overtemperature, input overvoltage, input undervoltage, output overvoltage, output short circuit, and output overload protection.

Feature Summary

• Integrated CCM boost PFC controller optimized for high efficiency across the load range
• Comprehensive multi-mode protection against electrical faults and thermal events
• Robust operation within wide universal AC input voltage ranges

Applications

• Power supplies for personal computers and printers
• LCD televisions and video game consoles
• High-power adapters and USB PD chargers
• Industrial control systems and home appliances

Procurement Notes

Verify component authenticity through authorized Power Integrations distributors or official channels. Confirm that the received units match the specified eSIP-16G package and HiperPFS-3 series designation. Request original manufacturer documentation to validate part history and ensure compliance with RoHS standards before integration into final designs.

Selection Notes

Select this component for designs requiring continuous conduction mode PFC performance with peak power capabilities around 120 W. Ensure the application environment accommodates the specified operating temperature range of -40 °C to 150 °C. Verify that the system topology aligns with the boost PFC architecture supported by the HiperPFS-3 family.

Part Context

The PFS7523L belongs to the HiperPFS-3 product line from Power Integrations, which specializes in high-performance power management integrated circuits. This series targets offline power supplies in the 75 W to 400 W range, offering high integration and thermal dissipation capabilities through specialized SIP packaging solutions for efficient heat transfer.

Replacement Considerations

The PFS7523H serves as a direct functional substitute within the same HiperPFS-3 series, sharing identical electrical characteristics and protection features while utilizing the eSIP-16D package variant.
