AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'TL' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure the source document explicitly lists this part number variant to avoid substitution errors with similar LinkSwitch-II devices.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring integrated power switching and control in a compact surface-mount package. It is suitable for low-power isolated applications where minimizing external component count is critical. Evaluate thermal performance requirements given the 150°C junction temperature limit and ensure the PCB layout supports the SO-8C footprint constraints.
