It accepts a wide supply range of 3V to 28V on Vcc (Vdd), making it suitable for systems powered from 5V, 12V, or 24V rails — common in industrial control, telecom, and battery-powered equipment. The controller drives an external transistor (Transistor Driver output type) and integrates synchronous rectification for improved efficiency. Its switching frequency is programmable from 200kHz to 500kHz, allowing the designer to trade off inductor size against switching losses. ## Key ratings and what they mean for the design The 3V to 28V supply range is the primary selection parameter: it determines which input bus the controller can regulate from. A 24V industrial supply rail sits comfortably within range, as does a 12V telecom bus or a 5V logic rail. The 200kHz to 500kHz switching frequency range gives flexibility — lower frequencies reduce switching losses but require larger magnetics; higher frequencies shrink the inductor and capacitor but increase gate-drive losses and may complicate EMI filtering. The -40°C to 85°C operating temperature range covers industrial and outdoor environments without needing a wider-temperature variant. Control features include current limit and soft start, which protect the external MOSFET and the load during startup and fault conditions. ## Lifecycle and sourcing The MAX8576EUB+ is listed as Active in production status. The part is ROHS3 compliant.","metaTitle":"MAX8576EUB+ Buck Controller, 3V to 28V Input, 200kHz-500kHz","metaDescription":"MAX8576EUB+ is an active step-down buck controller from Analog Devices. 3V to 28V supply, 200kHz-500kHz switching, -40°C to 85°C, 10-uMAX/uSOP.","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":"No","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":"Current Limit, Soft Start","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 500kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Supplier Device Package":"10-uMAX/uSOP","Voltage - Supply (Vcc/Vdd)":"3V ~ 28V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.92000","currency":"USD"},{"qty":10,"price":"$5.31200","currency":"USD"},{"qty":25,"price":"$5.02240","currency":"USD"},{"qty":100,"price":"$4.35260","currency":"USD"},{"qty":250,"price":"$4.12940","currency":"USD"},{"qty":500,"price":"$3.70528","currency":"USD"},{"qty":1000,"price":"$3.12494","currency":"USD"},{"qty":2500,"price":"$2.96869","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX8576-MAX8579.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX8576EUB+ a direct replacement for MAX8576EUB+T?","answer":"The MAX8576EUB+ and MAX8576EUB+T share the same electrical specifications and package.
