PFS7724L

Overview

The PFS7724L is a HiperPFS-4 family power factor correction controller featuring an integrated 600 V power MOSFET and gate driver in an eSIP-16G package. It operates in continuous conduction mode (CCM) with a switching frequency range of 22 kHz to 123 kHz. The device supports a supply voltage of 10.2 V to 15 V and functions within a junction temperature range of -40°C to 150°C. Designed for through-hole mounting, it eliminates external current sense resistors to reduce power loss.

Feature Summary

• Integrates a CCM boost PFC controller, gate driver, and 600 V power MOSFET in a single low-profile package
• Eliminates external current sense resistors using innovative control techniques to minimize power loss
• Adjusts switching frequency dynamically based on output load, input line voltage, and line cycle
• Features spread spectrum operation to minimize EMI filtering requirements across the entire load range

Applications

• High efficiency power factor correction stages in offline power supplies
• Industrial power conversion systems requiring wide load range efficiency
• Consumer electronics power adapters demanding low no-load consumption
• LED drivers and general purpose AC-DC converters

Procurement Notes

Verify component authenticity against Power Integrations official documentation before integration. Confirm that the eSIP-16G package orientation matches the PCB footprint design. Ensure thermal management strategies account for the 150°C maximum junction temperature rating during high-load operations. Cross-reference the specific ordering suffix with the manufacturer's latest datasheet to confirm pinout and electrical characteristics match the design requirements.

Selection Notes

Select this component when designing systems requiring integrated PFC and power stage functionality without external current sensing resistors. It is suitable for applications needing dynamic frequency adjustment to optimize efficiency at light loads and reduce EMI filter size. Consider the eSIP-16G package constraints for thermal dissipation and board space. Verify compatibility with the required input line voltage ranges and output power levels defined in the HiperPFS-4 family specifications.

Part Context

The PFS7724L belongs to the HiperPFS-4 series from Power Integrations, which combines digital control features with analog core techniques. This family targets high-performance power factor correction by integrating the controller, driver, and power switch. The design focuses on maximizing efficiency across varying load conditions while maintaining low standby power consumption through advanced line monitoring and feed-forward scaling capabilities.

Replacement Considerations

The PFS5175F-TL is documented as a similar substitute part number from Power Integrations. Verify functional equivalence and pin compatibility before substitution. Review the specific datasheets for both components to ensure electrical parameters and package dimensions align with the existing design constraints.
