Each phase handles roughly one-twelfth of the total load current. ## Control features and configuration Control features include current limit, enable, frequency control, phase control, and soft start. The controller does not require external programming or firmware — it is a pure analog controller configured through resistor dividers, timing capacitors, and feedback compensation. Clock sync input allows the switching frequency to be locked to an external clock, which helps manage EMI in noise-sensitive systems or synchronize multiple converters in a PolyPhase array. ## Package and mounting The part comes in a 48-lead LQFP with an exposed pad (48-eLQFP, 7x7 mm body). The exposed pad must be soldered to the PCB ground plane for thermal management — the 150°C TJ rating is only achievable with adequate pad-to-board heat sinking. Surface-mount assembly is straightforward with standard reflow profiles. ## Lifecycle and compliance The LTC3871HLXE-1#PBF is marked Active with no last-time-buy notice. ROHS3 compliant per. No PPAP documentation is cited in the ledger — if your program requires AEC-Q100 or PPAP, confirm with the manufacturer before committing the BOM. The part is available through independent distribution and quoted to order against an RFQ.","metaTitle":"LTC3871HLXE-1#PBF PolyPhase Bidirectional Buck-Boost","metaDescription":"Analog Devices LTC3871HLXE-1#PBF PolyPhase bidirectional buck-boost controller. 12 output phases, 60kHz-460kHz switching, 1.2V-100V supply, -40°C to 150°C TJ.","metaKeywords":null},"attributes":{"series":"PolyPhase®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"PolyPhase®","Package":"Tray","Function":"Step-Up, Step-Down","Topology":"Buck, Boost","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"12","Package / Case":"48-LQFP Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Current Limit, Enable, Frequency Control, Phase Control, Soft Start","Duty Cycle (Max)":"98%","Number of Outputs":"2","Output Configuration":"Positive","Frequency - Switching":"60kHz ~ 460kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Supplier Device Package":"48-eLQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.2V ~ 100V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$16.92000","currency":"USD"},{"qty":10,"price":"$15.54800","currency":"USD"},{"qty":25,"price":"$14.90360","currency":"USD"},{"qty":80,"price":"$13.13125","currency":"USD"},{"qty":250,"price":"$12.48680","currency":"USD"},{"qty":500,"price":"$11.68120","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/75050ae3a986b70abc1457274748ec9f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the LTC3871HLXE-1#PBF and what is it used for?","answer":"It is a PolyPhase bidirectional buck-boost controller from Analog Devices, capable of driving up to 12 output phases.
