It supports boost, buck, and flyback topologies, and the output is isolation-capable. The switching frequency is programmable from 3.5 kHz to 140 kHz, letting you trade transformer size against switching losses. A single transistor-driver output drives an external MOSFET, and synchronous rectification is built in — that recovers the diode-drop loss on the secondary side, which matters for efficiency above a few watts. Control features include current limit, enable, and soft start. The operating junction temperature range is -40°C to 125°C. ## Package and mounting — 20-TSSOP with 15 leads The LT8316IF#PBF comes in a 20-TSSOP package (0.173\" wide, 4.40 mm body) with 15 populated leads, surface-mount. The supplier device package is 20-TSSOP. It ships in Tube form. ## Lifecycle and supply posture The LT8316IF#PBF is listed as Active on the manufacturer's lifecycle record. There is no NRND or last-time-buy notice attached, so it remains a valid selection for new production builds. The part is ROHS3 compliant.","metaTitle":"LT8316IF#PBF Switching Regulator, 16V-560V Input","metaDescription":"LT8316IF#PBF from Analog Devices: 16V to 560V input, 3.5kHz-140kHz switching, flyback/buck/boost topology, isolation capable, -40°C to 125°C, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Function":"Step-Up, Step-Down, Step-Up/Step-Down","Topology":"Boost, Buck, Flyback","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width), 15 Leads","lifecycle_stage":"eol_hot","Control Features":"Current Limit, Enable, Soft Start","Number of Outputs":"1","Output Configuration":"Positive, Isolation Capable","Frequency - Switching":"3.5kHz ~ 140kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"16V ~ 560V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.99","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.99000","currency":"USD"},{"qty":10,"price":"$6.31300","currency":"USD"},{"qty":25,"price":"$6.01920","currency":"USD"},{"qty":100,"price":"$5.22640","currency":"USD"},{"qty":250,"price":"$4.99152","currency":"USD"},{"qty":500,"price":"$4.55112","currency":"USD"},{"qty":1000,"price":"$4.15500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6ea7258cad9dbdd798cb3c70d69fb997.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LT8316IF#PBF support flyback topology with no optocoupler?","answer":"Yes. The output configuration is isolation-capable, and the part is designed for no-opto flyback regulation.

Key differences: the LT3748 runs from a 5 V supply (not 16 V to 560 V), lacks synchronous rectification, and its operating temperature range tops out at 125°C or 150°C depending on suffix. The LT8316IF#PBF's wider input range and synchronous rectifier make it the better fit for high-voltage, higher-efficiency designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT8316IFPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT8316IFPBF when reusing this data.
