PFS7627L

Overview

The PFS7627L is a HiperPFS-4 power factor correction controller integrating a CCM boost PFC controller, gate driver, and 600 V power MOSFET in an InSOP-24 package. It operates at a switching frequency of 60 kHz with a maximum output power capability of 110 W. The device supports input voltages from 90 VAC and features low no-load consumption of 60 mW. Internal parasitic capacitance is specified at 320 pF. It functions within a temperature range of -40 °C to +125 °C.

Feature Summary

• Eliminates external current sense resistors by utilizing innovative control techniques that adjust switching frequency based on load and line conditions.
• Maximizes efficiency across the entire load range, particularly at light loads, while minimizing EMI filtering requirements through spread spectrum effects.
• Integrates advanced digital techniques for line monitoring and power factor enhancement alongside analog core control for ultra-low no-load power consumption.

Applications

• High-efficiency power supplies for consumer electronics
• Power adapters for computing equipment
• Industrial power conversion systems

Procurement Notes

Verify the specific suffix against official Power Integrations documentation to confirm pinout compatibility and thermal characteristics. Confirm RoHS compliance status via the manufacturer's environmental declaration. Ensure the selected package variant matches the intended PCB layout requirements for the InSOP-24 form factor.

Selection Notes

Select this component when designing compact power factor correction stages requiring integrated high-voltage switching without external sense resistors. The HiperPFS-4 architecture is suitable for applications demanding high efficiency at light loads and reduced electromagnetic interference through wide bandwidth spread spectrum operation.

Part Context

The PFS7627L belongs to the HiperPFS-4 family from Power Integrations. This series combines continuous conduction mode boost PFC control with a 600 V power MOSFET. The family is designed to simplify design and reduce component count by integrating gate driving and protection features into a single low-profile package.

Replacement Considerations

Consult official substitution guides for verified equivalents within the HiperPFS-4 or HiperPFS-3 families. Verify functional compatibility regarding voltage ratings and package dimensions before replacing existing designs.
