It switches at 250 kHz and integrates a 1.4 A rated switch, so the output power ceiling is set by the input voltage and the inductor's saturation current, not by an external FET. Input range spans 3 V to 28 V, covering single-cell Li-ion up to a 24 V industrial bus. Output is adjustable from 3 V up to 28 V via a resistor divider, with positive polarity only — no inverting or SEPIC topology here. ## Package and board-fit Supplied in a 16-lead SSOP (0.154-inch body width, 3.90 mm) and also listed under the supplier device package as 16-QSOP — the two are the same footprint with a slightly different body width (QSOP is nominally 3.90 mm wide, matching the SSOP-16). The surface-mount package suits medium-density boards where a small inductor and a few ceramic caps fit alongside. Shipping in tube format, not tape-and-reel — factor this into pick-and-place setup if your line expects reeled parts; a tube-to-reel transfer may be needed for high-volume assembly. ROHS3 compliant (no exempted substances), so no sunset risk on the RoHS exemption calendar. Not AEC-Q100 qualified — not intended for under-hood or chassis-mounted automotive designs.","metaTitle":"MAX618EEE+ Analog Devices Boost Regulator, 1.4A Switch","metaDescription":"MAX618EEE+ step-up boost regulator from Analog Devices. 1.4A switch, 3-28V input, adjustable output to 28V, 250kHz. 16-QSOP package.

That is a middle-band choice — low enough to keep switching losses moderate in the 1.4 A switch, high enough to use a small inductor (typically 10-22 µH) and output capacitor without excessive ripple. Above 300 kHz the internal switch losses climb; below 100 kHz the inductor grows."},{"question":"Does the MAX618EEE+ use synchronous rectification?","answer":"No — it uses an external Schottky diode as the rectifier. The absence of a synchronous FET means the diode forward drop (0.4-0.5 V typical) adds to the conduction loss, but the part avoids the complexity and cost of a second internal FET. Efficiency peaks in the 85-90% range at moderate loads."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX618EEE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX618EEE when reusing this data.
