Its 99.4% maximum duty cycle means the output can ride within millivolts of the input rail — useful when the input sags close to the target output voltage, such as during a battery discharge event. The switching frequency is programmable from 250 kHz to 530 kHz, letting you trade inductor size against switching losses; a higher frequency shrinks the magnetics but increases FET gate-drive losses. ## Synchronous rectification and control features for efficient sequencing Built-in synchronous rectification eliminates the external Schottky catch diode, improving efficiency at higher output currents — the bottom FET conducts during the off-time instead of a diode. Control features include an enable pin for power-up sequencing, a soft-start pin to limit inrush current, and a tracking input that lets the output follow another rail during startup — useful in multi-voltage FPGA or processor designs. The output configuration is positive and the driver signal is a transistor driver, meaning it drives external N-channel MOSFETs in a standard buck arrangement.","metaTitle":"LTC3834IGN-1#PBF Buck Controller, 4-36V, 16-SSOP","metaDescription":"Analog Devices LTC3834IGN-1#PBF step-down DC/DC controller, 4V to 36V input, 99.4% duty cycle, synchronous rectification, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Control Features":"Enable, Soft Start, Tracking","Duty Cycle (Max)":"99.4%","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"250kHz ~ 530kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Supplier Device Package":"16-SSOP","Voltage - Supply (Vcc/Vdd)":"4V ~ 36V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.62","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.62000","currency":"USD"},{"qty":10,"price":"$10.67900","currency":"USD"},{"qty":25,"price":"$10.23640","currency":"USD"},{"qty":100,"price":"$9.01910","currency":"USD"},{"qty":250,"price":"$8.57648","currency":"USD"},{"qty":500,"price":"$8.02314","currency":"USD"},{"qty":1000,"price":"$7.83000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a70d1250a291264dc19621b8f57ec607.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source to LTC3834IGN-1#PBF?","answer":"It drops into the same 16-SSOP footprint and pinout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC3834IGN-1~4PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC3834IGN-1~4PBF when reusing this data.
