PFS7536H

Overview

The PFS7536H is a HiperPFS-3 integrated power factor correction (PFC) controller designed for high-performance AC/DC conversion. It combines a CCM boost PFC controller, gate driver, and 600 V power MOSFET in an eSIP-16D package. The device supports peak power up to 610 W with an input voltage range of 180 VAC. It operates within a switching frequency range of 22 kHz to 123 kHz and functions reliably across a temperature range of -40°C to +150°C.

Feature Summary

• Integrates a continuous conduction mode (CCM) boost PFC controller, gate driver, and 600 V power MOSFET into a single low-profile package.
• Eliminates the need for external current sense resistors by utilizing innovative control techniques that adjust switching frequency based on load and line conditions.
• Features advanced digital techniques for line monitoring and feed-forward scaling while maintaining extremely low no-load power consumption through analog core control.
• Includes comprehensive protection mechanisms such as UV, OV, brown-in/out, hysteretic thermal shutdown, cycle-by-cycle current limit, and Safe Operating Area (SOA) protection.

Applications

• High-efficiency AC/DC power supplies
• Power factor correction stages in offline converters
• Industrial power management systems

Procurement Notes

Verify the specific suffix 'H' corresponds to the eSIP-16D package variant when ordering. Confirm RoHS compliance status and lead times directly with authorized distributors or Power Integrations. Ensure the application design accounts for the specified operating temperature range and thermal requirements associated with the integrated MOSFET structure.

Selection Notes

Select this component for designs requiring integrated PFC and power switching without external sense resistors. It is suitable for applications needing wide input voltage ranges and high reliability. Consider the eSIP-16D package constraints for PCB layout and thermal dissipation. Compare against other HiperPFS series members if different power levels or pin configurations are required.

Part Context

The PFS7536H belongs to the HiperPFS-3 family from Power Integrations. This series is characterized by high integration and efficiency in power factor correction applications. It is part of a broader lineup including variants like PFS7535H and PFS7534H, differentiated primarily by power handling capabilities and specific feature sets within the same architectural framework.

Replacement Considerations

Direct pin-compatible substitutes within the HiperPFS-3 family include PFS7535H and PFS7534H. Verify power ratings and package compatibility before substitution. Cross-family replacements require careful evaluation of electrical parameters and thermal performance.
