Procurement Notes

Verify the specific suffix GE2 indicates the tape and reel packaging format when ordering. Confirm that the application design strictly adheres to non-insulated topology requirements, as this component is not recommended for insulated topologies or automotive equipment. Ensure the input voltage stays within the specified 8.9 V to 26 V range for proper operation.

Selection Notes

Select this component for designs requiring a compact solution with integrated high-voltage switching capabilities. It is suitable for applications prioritizing low EMI through quasi-resonant operation. Consider the SOP-8 package constraints and the need for external current sense resistors for flexible power design. Verify compatibility with the required non-insulated architecture before implementation.
