It drives an external N-channel MOSFET — the output type is Transistor Driver — so the power stage is built around your choice of FET and inductor. The wide 4V to 60V supply range (Vcc/Vdd) means it can regulate from a 12V automotive battery, a 24V industrial rail, or a 48V telecom bus without a front-end pre-regulator. Switching frequency is adjustable between 200kHz and 600kHz, letting you optimise inductor size versus switching losses. Clock sync is available, so multiple rails can be phase-locked to reduce input ripple. The 100% duty-cycle capability allows near-zero dropout when the input falls close to the output voltage. Operating junction temperature spans -40°C to 125°C, covering under-hood automotive and factory-floor environments. ## Integration note — package and thermal The 10-MSOP-EP (exposed pad) package requires a thermal land on the PCB. The exposed pad must be soldered to a copper plane for adequate heat transfer — the datasheet's recommended footprint is a 3mm × 3mm pad with at least four thermal vias to the ground plane. The part is surface-mount, so it reflows with standard lead-free profiles. The Tube shipment means the parts are aligned in a plastic tube; for automated pick-and-place, transfer to tape-and-reel is needed unless your feeder accepts tubes. The 10-pin MSOP footprint is compact — 3mm × 3mm body — so board area is tight, but the exposed pad adds a thermal path that keeps junction temperature within the -40°C to 125°C range even at higher switching frequencies.","metaTitle":"LTC3824IMSE#PBF Buck Controller, 4V–60V, 200kHz–600kHz","metaDescription":"LTC3824IMSE#PBF is an active-production step-down (buck) DC/DC controller from Analog Devices.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Frequency Control, Soft Start","Duty Cycle (Max)":"100%","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 600kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Supplier Device Package":"10-MSOP-EP","Voltage - Supply (Vcc/Vdd)":"4V ~ 60V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.78","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.78000","currency":"USD"},{"qty":10,"price":"$6.12400","currency":"USD"},{"qty":25,"price":"$5.83880","currency":"USD"},{"qty":100,"price":"$5.06980","currency":"USD"},{"qty":250,"price":"$4.84192","currency":"USD"},{"qty":500,"price":"$4.41472","currency":"USD"},{"qty":1000,"price":"$3.84507","currency":"USD"},{"qty":2500,"price":"$3.70266","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/3824fh.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for LTC3824IMSE#PBF?","answer":"The LTC3864EMSE#PBF is the closest functional peer — same buck topology, 100% duty cycle, single output, transistor-driver output, and -40°C to 125°C temperature grade. The key difference is switching frequency: the LTC3824 is adjustable 200kHz–600kHz, while the LTC3864 is fixed at 50kHz and adds current limit, enable, and power-good features. The LTC3864EMSE#PBF is a drop-in candidate if the design can accept a fixed 50kHz switch and wants those extra control features."},{"question":"What compliance documentation does Analog Devices provide for LTC3824IMSE#PBF?","answer":"The LTC3824IMSE#PBF is ROHS3 compliant (lead-free). Analog Devices provides a RoHS certificate of compliance and a material declaration upon request. The part does not carry UL or IEC certification markings — those are typically system-level, not component-level, approvals."},{"question":"Will LTC3824IMSE#PBF drop into a panel specified around LTC3864EMSE#PBF without rewiring?","answer":"The LTC3824IMSE#PBF shares the same 10-MSOP-EP package and pinout as the LTC3864EMSE#PBF, so it is a mechanical drop-in. However, the LTC3864 adds current limit, enable, and power-good pins that the LTC3824 does not have — those pins may be left floating or pulled to the appropriate rail depending on the board layout. The switching frequency also differs (adjustable vs fixed 50kHz), so the inductor and compensation network may need re-tuning. A board-level review is recommended before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC3824IMSEPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC3824IMSEPBF when reusing this data.
