Its 2V to 28V input range covers battery voltages from a deeply discharged cell through the full charge level, and the adjustable 0.925V to 2V output handles processor core and I/O rails. The single-output architecture means one controller per voltage rail — a design choice that simplifies loop compensation at the cost of board area. ## Package and layout: 24-SSOP vs 24-QSOP These two codes refer to the same mechanical footprint — the QSOP is a thinner variant of the SSOP with the same 0.0256\" pin pitch and body dimensions. A layout drawn for one accepts the other without a board spin. The Bulk packaging means the part ships in tubes or trays, not tape-and-reel — a consideration for pick-and-place throughput but irrelevant for prototype or low-volume builds. ## Lifecycle and compliance reality One constraint: the part is RoHS non-compliant. This means it contains lead (Pb) above the 0.1% threshold, which blocks it from EU RoHS-exempted markets unless the buyer holds a valid exemption. For non-EU builds or legacy BOMs that already specify leaded solder, this is not a blocker — but it must be flagged at the procurement desk.","metaTitle":"MAX1854EEG Analog Devices Step-Down Controller, 2V-28V Input","metaDescription":"MAX1854EEG step-down controller from Analog Devices, 2V to 28V input, 0.925V to 2V output, 24-SSOP/QSOP.
