The SOT-23-6 package keeps the footprint small, but thermal performance depends on the external MOSFET and diode — those components see the real dissipation. ## Sourcing and lifecycle Lifecycle status is Active per the manufacturer, with ROHS3 compliance. For volume commitments or BOM freeze planning, this is a stable line — no imminent obsolescence signal.","metaTitle":"MAX1523EUT+T Boost/Flyback/SEPIC Controller, SOT-23-6","metaDescription":"MAX1523EUT+T is a step-up/step-down controller IC supporting boost, flyback, and SEPIC topologies. 2.5V–5.5V supply, 85% duty cycle, SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up, Step-Up/Step-Down","Topology":"Boost, Flyback, SEPIC","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Control Features":"Enable","Duty Cycle (Max)":"85%","Number of Outputs":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"No","Supplier Device Package":"SOT-6","Voltage - Supply (Vcc/Vdd)":"2.5V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.52","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.52000","currency":"USD"},{"qty":10,"price":"$4.06200","currency":"USD"},{"qty":25,"price":"$3.84040","currency":"USD"},{"qty":100,"price":"$3.32850","currency":"USD"},{"qty":250,"price":"$3.15776","currency":"USD"},{"qty":500,"price":"$2.83346","currency":"USD"},{"qty":1000,"price":"$2.38966","currency":"USD"},{"qty":2500,"price":"$2.27018","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1522-MAX1524.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact function of MAX1523EUT+T?","answer":"It is a current-mode PWM controller IC that drives an external transistor in boost, flyback, or SEPIC converters.
