It integrates synchronous rectification, which eliminates the external Schottky catch diode and improves efficiency at lower output voltages. Switching frequency runs up to 350 kHz, allowing a reasonable inductor size for the 2A output. ## Output voltage and package fit Output is adjustable (programmable) with a minimum fixed option of 1.1V, and preset taps at 2.525V and 3.33V — the external feedback divider sets the final voltage up to 5.5V. ## Active production and compliance status RoHS3 compliant (2011/65/EU + 2015/863), with no added REACH SVHC above threshold per the manufacturer's declaration.","metaTitle":"MAX1644EAE+ Buck Regulator, 2A, 16-SSOP, Active","metaDescription":"Analog Devices MAX1644EAE+ step-down buck regulator, 2A output, up to 350kHz switching, adjustable output, 16-SSOP, active production, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable (Programmable)","Mounting Type":"Surface Mount","Package / Case":"16-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"Up to 350kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"16-SSOP","Voltage - Output (Min/Fixed)":"1.1V (2.525V, 3.33V)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.07","stockQuantity":16,"priceTiers":[{"qty":1,"price":"$13.07000","currency":"USD"},{"qty":10,"price":"$12.00800","currency":"USD"},{"qty":25,"price":"$11.51000","currency":"USD"},{"qty":100,"price":"$10.14120","currency":"USD"},{"qty":250,"price":"$9.64348","currency":"USD"},{"qty":500,"price":"$9.02132","currency":"USD"},{"qty":1000,"price":"$8.27473","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the output current and voltage range for MAX1644EAE+?","answer":"It delivers 2A continuous output with an adjustable range from 1.1V up to 5.5V, using an external feedback divider."},{"question":"What package does MAX1644EAE+ come in?","answer":"It is supplied in a 16-lead SSOP package (0.209\" body width, 5.30mm) on tube."},{"question":"What compliance documentation does Analog Devices provide for MAX1644EAE+?","answer":"The part is ROHS3 compliant and the manufacturer provides a full RoHS certificate and material declaration upon request."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1644EAE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1644EAE when reusing this data.
