The small footprint favours dense layouts but requires careful solder-paste stencil design and X-ray inspection for voiding under the bumps. ## Active lifecycle, no PCN watch needed ROHS3 compliant per, with no REACH or conflict-minerals restrictions flagged in this listing.","metaTitle":"TI LM3530UMX-40/NOPB Boost LED Driver, 40V, 12-DSBGA","metaDescription":"Texas Instruments LM3530UMX-40/NOPB DC-DC boost regulator, 500kHz PWM dimming, 30mA/ch, 40V output.
