It operates from a 4.5V to 30V supply rail, covering 5V, 12V, and 24V industrial buses as well as battery-powered systems. Switching frequency is pin-selectable between 150 kHz and 300 kHz, and the part supports external clock synchronization to align switching edges with other converters in the system — useful for avoiding beat-frequency ripple in multi-rail designs. The controller includes an enable input and a soft-start feature for controlled ramp-up, plus a synchronous rectifier driver to improve efficiency by replacing the freewheeling diode with a low-Rds(on) MOSFET. ## Output configuration and duty cycle Two outputs are available — the controller can drive two independent converter stages or a dual-phase rail for higher output current with reduced ripple. The output configuration is positive, and the maximum duty cycle reaches 98%, allowing near-dropout operation when the input voltage is close to the output. The single-phase topology keeps the external component count low: one inductor, one sense resistor, and a pair of MOSFETs per output. The 16-pin SSOP (3.90 mm width) or QSOP package fits compact PCB layouts typical of space-constrained industrial and telecom power stages. ## Temperature grade and deployment context The controller itself does not carry the pass-element heat — the external MOSFETs and inductor handle the thermal load, so board layout and airflow determine the final power capability.","metaTitle":"MAX1654EEE+ Buck Controller, 4.5-30V, 150/300kHz, 16-QSOP","metaDescription":"Active-production step-down buck controller from Analog Devices. 4.5V-30V input, 150/300kHz switching, synchronous rectifier, industrial temp range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Control Features":"Enable, Soft Start","Duty Cycle (Max)":"98%","Number of Outputs":"2","Output Configuration":"Positive","Frequency - Switching":"150kHz, 300kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Supplier Device Package":"16-QSOP","Voltage - Supply (Vcc/Vdd)":"4.5V ~ 30V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.80000","currency":"USD"},{"qty":10,"price":"$7.94800","currency":"USD"},{"qty":25,"price":"$7.57800","currency":"USD"},{"qty":100,"price":"$6.57990","currency":"USD"},{"qty":250,"price":"$6.28424","currency":"USD"},{"qty":500,"price":"$5.72972","currency":"USD"},{"qty":1000,"price":"$4.99041","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1654EEE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1654EEE when reusing this data.
