Each of its two outputs delivers up to 400 mA at a regulated 39.5 V maximum, with internal switches handling the boost conversion at a fixed 1 MHz switching frequency. PWM dimming is supported directly on the control pin, giving the designer a linear brightness control loop without external DACs or complex sequencing — the part's own dimming input accepts a logic-level PWM signal and modulates the LED current accordingly. ## Package, footprint, and thermal reality The tape-and-reel variant (TR suffix) ships in standard 7-inch reels, suitable for automated pick-and-place. The cut-tape option (CT) is also available from the same supply chain for prototype or low-volume builds. ## Sourcing and lifecycle — active part, traceable supply No end-of-life notice or last-time-buy date has been issued. The part is ROHS3 compliant per the manufacturer's declaration. The tube-packaged sibling LT3466EDD#PBF is electrically identical but ships in a different carrier — the die, package, and parametric performance are the same. The LT3466EDD-1#PBF variant carries a different switching frequency or UVLO threshold; confirm the specific revision before substituting. Sourced through independent distribution channels. No stock-holding claim is made; each RFQ is handled on its own terms.","metaTitle":"LT3466EDD#TRPBF Analog Devices Dual Boost LED Driver, 400mA","metaDescription":"Active dual-output step-up LED driver, 39.5V output, 400mA per channel, PWM dimming, 1MHz switching, -40 to 85°C. 10-DFN package.
