LED Driver IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as required by project specifications. Check for obsolete status or lifecycle changes directly with the manufacturer or authorized distributors before finalizing design-in decisions.

LED Driver IC Selection Notes

Select this component for portable devices requiring multiple regulated rails from a single input. The high output count reduces external component count. Ensure the 49-WLP package fits the PCB footprint constraints. Verify that the 6.8mA quiescent current meets system power budget requirements.
