LED Driver IC Procurement Notes

Verify the part status carefully as this specific variant is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure the package type matches the 12-WFDFN specification with an exposed pad for proper thermal management and PCB layout compatibility during integration.

LED Driver IC Selection Notes

Select this component when a buck topology is required for driving LEDs from higher voltage rails up to 65V. The 2A current capability suits moderate-power LED strings. Consider the 400kHz frequency trade-off between efficiency and component size. Verify that the narrow output voltage regulation window aligns with the specific LED forward voltage requirements of the target application.
