Procurement Notes

Verify the Not Recommended for New Designs (NRND) status before finalizing any schematic or procurement plan. Confirm availability through authorized distributors as standard stock may be limited. Ensure all electrical parameters align with existing system requirements to avoid obsolescence risks during production lifecycle management.

Selection Notes

Select this component when designing circuits for small panel backlights requiring multi-channel drive capability. Consider the 1 MHz switching frequency for EMI management and the specific thermal dissipation limits. Evaluate the 30 mA per channel limit against total LED string requirements to ensure adequate headroom without exceeding maximum ratings.
