Procurement Notes

Verify the component status before procurement, as related models in this series may carry Not Recommended for New Designs (NRND) classifications. Confirm that the specific ZLS4 suffix matches the required pinout and thermal specifications for your PCB layout. Ensure compatibility with existing supply chains given potential lifecycle changes in the Lumissil product portfolio.

Selection Notes

Select this component when designing circuits requiring high-channel count LED driving with boost topology capabilities. Consider the 120 mA per channel limit and the 40 V maximum input voltage when sizing external components. Evaluate the 16-TSSOP package constraints against available board space and thermal dissipation requirements for the target application environment.
