AC DC Converters, Offline Switchers Procurement Notes

Verify that the specific part number corresponds to the legacy HiperTFS series rather than newer generations. Confirm compatibility with existing thermal management designs due to the eSIP package characteristics. Ensure design documentation references the correct datasheet version for accurate electrical parameters and pin configurations during procurement validation.

AC DC Converters, Offline Switchers Selection Notes

Select this component for applications requiring simultaneous high-power forward and low-power flyback conversion within a compact form factor. Consider its integration benefits for reducing bill-of-materials complexity. Evaluate thermal performance requirements given the single-package power density. Verify input voltage range compatibility with system specifications before finalizing selection.

AC DC Converters, Offline Switchers Part Context

This part belongs to the discontinued HiperTFS series, which was succeeded by the HiperTFS-2 generation. Power Integrations announced discontinuation after June 10, 2020. Engineers should consider alternative devices from the newer series for new designs while maintaining support for existing legacy systems using this component.
