The wide 76V maximum input covers 48V telecom buses, 24V industrial supplies, and 12V automotive systems with headroom for transients — no external clamp needed for load-dump events up to the rated ceiling. ## 127 kHz switching frequency and the no-synchronous-rectifier trade-off Switching at 127 kHz, the part uses a lower frequency than modern high-density converters — the external inductor and output capacitor are physically larger, but switching losses in the internal FET are lower, which matters for thermal management in the 16-TQFN (5x5 mm) exposed-pad package. The absence of a synchronous rectifier means the freewheeling diode is external — a Schottky with a forward voltage below 0.5V at 2A keeps efficiency in the 80-85% range typical for this topology, but the diode's reverse leakage at high temperature adds to the quiescent draw. ## Active production — ROHS3 compliant, no PCN watch needed ROHS3 compliant per the entry, and the 16-WQFN exposed-pad package with a 5x5 mm footprint is a standard Analog Devices TQFN format — the laser etch and date-code trace cleanly to the authorized supply chain.","metaTitle":"MAX5090AATE+ Analog Devices Buck Regulator, 3.3V Fixed, 2A","metaDescription":"MAX5090AATE+ from Analog Devices: 76V input step-down buck regulator, fixed 3.3V output at 2A, 127kHz switching, -40 to +125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"16-WQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"127kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"76V","Voltage - Input (Min)":"6.5V","Supplier Device Package":"16-TQFN (5x5)","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.96","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.96000","currency":"USD"},{"qty":10,"price":"$11.91000","currency":"USD"},{"qty":25,"price":"$11.41640","currency":"USD"},{"qty":100,"price":"$10.05890","currency":"USD"},{"qty":250,"price":"$9.56520","currency":"USD"},{"qty":500,"price":"$8.94810","currency":"USD"},{"qty":1000,"price":"$8.20756","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What package does the MAX5090AATE+ come in?","answer":"The supplier device package designation is 16-TQFN (5x5).
