It delivers a 1.5A internal switch at a 2.7MHz switching frequency, which keeps external inductor and capacitor values small — useful for compact portable designs. Input voltage range spans 2.45V to 16V, and the adjustable output can go as high as 35V. The 2.45V minimum input matches the reference voltage, so the part starts up from a single lithium-ion cell or a 3.3V rail. Operating temperature is rated 0°C to 70°C — a commercial-grade window suited for bench supplies, telecom line cards, and other indoor equipment. The synchronous rectifier is external (not integrated), so layout needs a Schottky diode in the power path. ## Package and board-fit considerations Housed in an 8-MSOP with exposed pad (8-MSOP-EP), the package measures 3.00mm x 3.00mm. Supplied in tube packaging, the LT1946AEMS8E#PBF is a surface-mount part. The 0.118-inch body width (3.00mm) fits standard MSOP-8 footprints; the exposed pad adds a fifth thermal connection underneath.","metaTitle":"LT1946AEMS8E#PBF Boost/SEPIC Regulator, 1.5A Switch, 2.7MHz","metaDescription":"LT1946AEMS8E#PBF adjustable boost/SEPIC regulator, 1.5A switch, 2.7MHz, 8-MSOP-EP.
