It uses a step-down (buck) topology and supports analog dimming, making it a straightforward choice for dimmable LED lamps and luminaires where the control signal is a 0–10 V or similar analog level. The part operates from an 8V to 13V supply rail, which typically comes from a rectified and filtered AC line or a pre-regulator. With a single output and no internal power switch, the external MOSFET and inductor are sized by the designer for the target LED current. ## Temperature range and package — storage and assembly notes Rated for -40°C to 125°C junction temperature, this part handles outdoor and industrial lighting fixtures where the ambient can swing wide. The 10-VSSOP package (3.00 mm width) is a small outline, so board space is tight — good for compact bulb replacements and linear fixtures. Surface-mount assembly is standard; store the reels dry if the moisture-seal bag is breached, as MSL 3 parts need a bake before reflow after floor-life exposure. ## Lifecycle and sourcing reality Listed as Active with RoHS3 compliance.","metaTitle":"LM3444MM/NOPB AC DC Offline Switcher, Analog Dimming","metaDescription":"Texas Instruments LM3444MM/NOPB AC DC Offline Switcher for LED lighting.
