AC DC Converters, Offline Switchers Procurement Notes

Verify part status carefully as distributor records indicate this specific model may be discontinued or subject to supply limitations. Confirm availability directly with Power Integrations or authorized distributors before finalizing procurement plans. Ensure the suffix matches required packaging specifications.

AC DC Converters, Offline Switchers Selection Notes

Select this component for applications requiring integrated flyback conversion up to 35 W. The InnoSwitch-EP series offers reduced external component count compared to discrete solutions. Verify that the 100 kHz switching frequency and eSOP-R16B package align with thermal and spatial constraints of the target design.

AC DC Converters, Offline Switchers Part Context

The INN2605K belongs to the InnoSwitch-EP family, which combines a high-voltage MOSFET with a proprietary control IC. This integration simplifies the design of isolated AC/DC converters by eliminating the need for secondary-side feedback components and optocouplers, reducing bill of materials and assembly complexity.

AC DC Converters, Offline Switchers Replacement Considerations

Check for updated revisions within the InnoSwitch-EP family. Consult official substitution guides for pin-compatible alternatives if this specific part number is unavailable.
