It delivers up to 40V output from a 3.15V to 5.5V input rail, with an integrated switch rated for 970mA peak current — enough to drive a string of series-connected LEDs without an external FET. Dimming is handled either by analog current adjustment or PWM input, giving the designer flexibility between smooth brightness control and high-efficiency pulse-width modulation. The 40V output ceiling means it handles up to roughly 10-12 white LEDs in series, depending on forward voltage drop. ## Package, temperature, and board-fit Housed in an 8-pin WDFN with exposed pad (8-TDFN, 3x3mm), the MAX1554ETA+T requires a surface-mount reflow profile. The part is available in tape-and-reel or cut-tape formats, which matters for prototype builds vs production reels. ROHS3 compliant, no lead or halogen restrictions to flag for EU shipments. ## Active production and sourcing reality No pin-compatible second-source is documented from the manufacturer, so the BOM carries single-source risk — something to flag if volume ramps.","metaTitle":"MAX1554ETA+T Analog Devices LED Driver, 40V Boost, 970mA","metaDescription":"MAX1554ETA+T active-production LED driver IC from Analog Devices.
