Switching frequency is programmable from 100kHz to 500kHz, and the built-in clock sync lets multiple regulators share a common timing reference. The single transistor-driver output delivers a duty cycle up to 90%, configured for positive or isolation-capable output schemes. This part is rated for the -40°C to 85°C industrial temperature range, making it suitable for telecom, industrial power supplies, and battery-powered equipment where a wide input range is needed. ## Package and mounting Housed in a 10-pin uMAX/uSOP package (3.00 mm width, 0.118\" pitch), surface-mount only. Tape & Reel (TR) and Cut Tape (CT) are available. ## Lifecycle and procurement posture The MAX669EUB+T carries an Active product status with ROHS3 compliance. This part is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"MAX669EUB+T IC Regulator Controller, Boost/Flyback/SEPIC","metaDescription":"MAX669EUB+T from Analog Devices is an active, multi-topology PWM controller supporting Boost, Flyback, and SEPIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Signal Isolation"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up, Step-Up/Step-Down","Topology":"Boost, Flyback, SEPIC","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Control Features":"Enable, Frequency Control","Duty Cycle (Max)":"90%","Number of Outputs":"1","Output Configuration":"Positive, Isolation Capable","Frequency - Switching":"100kHz ~ 500kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"No","Supplier Device Package":"10-uMAX/uSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 28V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.59","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.59000","currency":"USD"},{"qty":10,"price":"$5.95000","currency":"USD"},{"qty":25,"price":"$5.67320","currency":"USD"},{"qty":100,"price":"$4.92600","currency":"USD"},{"qty":250,"price":"$4.70456","currency":"USD"},{"qty":500,"price":"$4.28948","currency":"USD"},{"qty":1000,"price":"$3.73599","currency":"USD"},{"qty":2500,"price":"$3.59762","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX668-MAX669.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can MAX669EUB+T be used in a SEPIC converter?","answer":"Yes, the SEPIC topology is explicitly listed among the supported topologies, alongside Boost and Flyback."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX669EUBT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX669EUBT when reusing this data.
