PFS7623H

Overview

The PFS7623H is a HiperPFS-4 family power factor correction controller integrating a continuous conduction mode boost PFC controller, gate driver, and 600 V power MOSFET. It operates at a switching frequency of 60 kHz with a supply voltage range of 5 V to 12 V. The device utilizes an eSIP package with 16 pins, measuring 16 mm in length and 1.96 mm in height. It supports surface mount installation and functions within a temperature range of -40 °C to 150 °C.

Feature Summary

• Integrates 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 for efficiency optimization
• Features spread spectrum effect to minimize EMI filtering requirements across wide bandwidth
• Includes comprehensive protection mechanisms such as UV, OV, brown-in/out, and thermal shutdown

Applications

• High-efficiency power factor correction stages in AC-DC converters
• Compact power supplies requiring reduced component count
• Applications demanding low no-load power consumption
• Systems needing enhanced load transient response

Procurement Notes

Verify the specific suffix against official Power Integrations documentation to confirm exact electrical characteristics and packaging options. Ensure compatibility with your PCB layout regarding the eSIP-16 footprint. Confirm that the 600 V rating aligns with your circuit's peak voltage stresses. Check for any recent product change notices affecting assembly or sourcing.

Selection Notes

Select this component when designing systems requiring integrated PFC and power switching without external sense resistors. Consider its 60 kHz operation for balancing efficiency and EMI performance. Evaluate the eSIP package size constraints against your enclosure dimensions. Verify that the 150 °C junction temperature capability meets your thermal management strategy.

Part Context

The PFS7623H belongs to the HiperPFS-4 series from Power Integrations. This family focuses on high-density power conversion by combining control logic and power devices. It targets applications where space savings and simplified design are critical priorities over discrete component solutions.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the HiperPFS family. Verify that any substitute maintains the 600 V MOSFET rating and eSIP-16 package form factor.
