It drives external N-channel MOSFETs from a single supply rail of 4.5 V to 38 V, making it a fit for intermediate bus conversion in industrial, automotive, and telecom equipment where the input voltage can swing above and below the regulated output. The controller operates over a -40°C to 150°C junction temperature range, so it can sit on a board near a hot power stage or inside an engine-bay enclosure without derating concerns. ## Switching frequency and output flexibility Two independent switching-frequency ranges are available: a wide band from 115 kHz to 835 kHz, and a narrower band from 350 kHz to 535 kHz. The lower end suits designs where efficiency and thermal management take priority; the upper end shrinks the magnetics and output capacitors. Each of the two outputs can be configured independently as a buck or a boost, and the controller supports a maximum duty cycle of 96% for the buck channel and 99% for the boost channel. Control features include enable, frequency control, power-good flag, soft-start, and tracking — enough to sequence multiple rails without an external supervisor. ## Package and mounting Housed in a 32-lead WFQFN with exposed pad (5 mm × 5 mm body), the LTC7812HUH#PBF is a surface-mount part. The exposed pad must be soldered to a thermal land on the PCB — the datasheet layout recommendation shows a grid of vias under the pad to pull heat into the inner copper planes. The part ships in a tube; if your pick-and-place line expects tape-and-reel, confirm the reel option (LTC7812HUH#TRPBF) before ordering. ## Lifecycle and sourcing Marked as Active on the manufacturer's product status. No last-time-buy or end-of-life notice is in effect. The part is ROHS3 compliant. For BOM planning, this means no forced redesign from obsolescence in the near term.","metaTitle":"LTC7812HUH#PBF Buck-Boost Controller, 32-QFN, Active","metaDescription":"LTC7812HUH#PBF is an active dual-output buck-boost controller from Analog Devices. 4.5V-38V supply, -40°C to 150°C junction temp, 32-QFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Function":"Step-Up, Step-Down","Topology":"Buck, Boost","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"32-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable, Frequency Control, Power Good, Soft Start, Tracking","Duty Cycle (Max)":"96%, 99%","Number of Outputs":"2","Output Configuration":"Positive","Frequency - Switching":"115kHz ~ 835kHz, 350kHz ~ 535kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"No","Supplier Device Package":"32-QFN (5x5)","Voltage - Supply (Vcc/Vdd)":"4.5V ~ 38V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.62","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.62000","currency":"USD"},{"qty":10,"price":"$10.68200","currency":"USD"},{"qty":25,"price":"$10.23920","currency":"USD"},{"qty":100,"price":"$9.02170","currency":"USD"},{"qty":250,"price":"$8.57896","currency":"USD"},{"qty":500,"price":"$8.02546","currency":"USD"},{"qty":1000,"price":"$7.36128","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/7812fc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the LTC7812HUH#PBF datasheet?","answer":"The full datasheet from Analog Devices covers the pinout, application circuits, inductor selection, and thermal layout for the 32-QFN package.
