LED Driver IC Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package type and tape/reel specifications. Confirm that the procurement source provides valid AEC-Q100 certification records. Check for moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with your manufacturing process regarding the HTSSOP-20 footprint dimensions.

LED Driver IC Selection Notes

Select this component when designing systems requiring two isolated LED channels driven by a single controller. It is suitable for applications where input voltage fluctuates significantly, necessitating SEPIC capability alongside standard boost operation. Consider the 2.2 MHz fixed frequency for EMI filtering design constraints. Evaluate thermal performance based on the 160 mA output current capability and the specific PCB copper area available for heat dissipation in the HTSSOP-20 package.
