LED Driver IC Procurement Notes

Verify the specific suffix 'TP+' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and pin assignment. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with Analog Devices documentation to validate availability status and lead times before finalizing procurement plans.

LED Driver IC Selection Notes

Select this component when designing circuits requiring dual-channel LED drive with high input voltage tolerance. It is suitable for applications needing both boost and SEPIC topology support within a single IC. Consider the 20-pin QFN package constraints for thermal management and PCB layout. Verify that the required switching frequency range aligns with external inductor and capacitor selections.

LED Driver IC Part Context

This device belongs to the MAX16838 family of LED drivers manufactured by Analog Devices Inc./Maxim Integrated. It is designed specifically for high-efficiency lighting solutions where space and component count are critical. The integration of dual channels and multiple topologies reduces the bill of materials compared to discrete solutions.

LED Driver IC Replacement Considerations
