The dual positive-and-negative output configuration means a single IC generates the bipolar rails needed for op-amp supplies, LCD bias, or sensor front-ends without a separate inverting stage. ## Topology flexibility and output limits The LT3487 supports boost, charge pump, and Cuk topologies — the charge pump mode generates a negative rail from a positive input without a magnetic component, while the Cuk topology provides a regulated inverted output with continuous input and output current. Output voltage adjusts from a 1.23 V reference up to 28 V maximum, so the same part serves a 3.3 V logic rail on one channel and a 24 V bias supply on the other. No synchronous rectifier means the external Schottky diode selection matters — a 1 A, 30 V Schottky with low forward drop keeps efficiency above 80% across most of the load range. ## Sourcing and cross-reference reality The single-output LT3579EFE#TRPBF delivers higher switch current (6 A) but lacks the second channel — it fits applications needing a single high-power rail, not the dual-rail requirement the LT3487 serves.","metaTitle":"LT3487EDD#TRPBF Dual Rail Regulator, Boost/Charge Pump/Cuk","metaDescription":"Analog Devices LT3487EDD#TRPBF dual-output adjustable regulator, 2.3-16V input, 750mA/900mA switches, 2 MHz switching frequency, 10-DFN package, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up, Step-Up/Step-Down","Topology":"Boost, Charge Pump, Cuk","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"750mA (Switch), 900mA (Switch)","Number of Outputs":"2","Output Configuration":"Positive and Negative (Dual Rail)","Frequency - Switching":"2MHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"16V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"28V","Supplier Device Package":"10-DFN (3x3)","Voltage - Output (Min/Fixed)":"1.23V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.01","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.01000","currency":"USD"},{"qty":10,"price":"$6.33600","currency":"USD"},{"qty":25,"price":"$6.04080","currency":"USD"},{"qty":100,"price":"$5.24530","currency":"USD"},{"qty":250,"price":"$5.00956","currency":"USD"},{"qty":500,"price":"$4.56754","currency":"USD"},{"qty":1000,"price":"$4.17000","currency":"USD"},{"qty":2500,"price":"$4.17000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/61f19dff5fb60d2422f62c73e424550a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Analog Devices provide for the LT3487EDD#TRPBF?","answer":"The LT3487EDD#TRPBF is RoHS3 compliant with no lead exemptions.
