LED Driver IC Procurement Notes

Verify the specific suffix when ordering. The 'D' variant typically denotes a tape-and-reel packaging format, whereas the base part number may refer to tube packaging. Confirm the exact ordering part number with the manufacturer or distributor to ensure compatibility with automated assembly processes and moisture sensitivity levels.

LED Driver IC Selection Notes

Select this component for low-power LED applications requiring high integration. It is suitable for designs needing support for both isolated and non-isolated topologies. Consider the 146 mA output capability and 66 kHz operating frequency when designing magnetic components. Ensure the thermal management strategy aligns with the SO-8C package constraints.
