Switching at 1 MHz, it allows the use of small inductors and ceramic capacitors, shrinking the footprint for space-constrained portable displays. The part is RoHS non-compliant, which may restrict its use in new designs requiring RoHS exemption or in regions enforcing strict RoHS compliance. We source this part through our independent supply chain against an RFQ — confirm the BOM quantity and we will quote current market availability and pricing.","metaTitle":"LM3502SQ-16 Obsolete TI LED Driver – Sourcing & Replacement","metaDescription":"LM3502SQ-16 is obsolete.
