PFS7628H

Overview

The PFS7628H is a high-power Power Factor Correction (PFC) controller from the HiperPFS-3 series by Power Integrations. It delivers a continuous output power of 350W at 90VAC input and a peak output power of 385W. The device operates with a supply voltage range of 10.2V to 15V and features an operating current of 1.07 mA. It functions at a switching frequency of 123 kHz. The component is housed in an eSIP-16 package, designed for universal input applications without an integrated diode.

Feature Summary

• Integrates a 600 V MOSFET for compact boost PFC form factors
• Maintains high efficiency and power factor across the entire load range
• Optimized packaging supports high-density designs

Applications

• Universal input power supplies
• High density AC/DC converters
• Power factor correction stages in consumer electronics

Procurement Notes

Verify the specific package variant, as HiperPFS-3 devices are available in different pinout configurations such as H and L packages. Confirm that the selected unit matches the required thermal and electrical specifications for the target application. Ensure compatibility with existing bill of materials and design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring up to 350W continuous output power with high power factor correction. The integrated 600V MOSFET reduces external component count compared to discrete solutions. Consider the eSIP-16 package for thermal management requirements and board space limitations in high-density power supply architectures.

Part Context

The PFS7628H belongs to the HiperPFS-3 family, which combines PFC control with power switching capabilities. This integration simplifies the design of single-stage or two-stage power supplies. The series targets applications demanding high reliability and efficiency in universal input environments, providing a robust solution for modern power conversion needs.

Replacement Considerations

Check datasheets for compatible alternatives within the HiperPFS-3 series, such as the PFS7528H, noting differences in peak power ratings and package types. Verify pin compatibility and thermal characteristics when substituting to ensure seamless integration into existing designs.
