It integrates an 850 mA switch rated to 100 V, with a 75 V input bus and a switching frequency between 12 kHz and 60 kHz. Output is adjustable from 1.244 V up to the switch voltage limit, and the configuration supports positive, negative, or isolated rails. It ships in a TO-220-5 through-hole package. ## 850 mA switch — what it means for your power budget The 850 mA figure is the peak switch current, not the continuous output. In a boost converter, output current will be lower by the voltage-conversion ratio times efficiency. ## Wide input range and output flexibility The input range spans 3 V to 75 V. The switch can handle up to 100 V. Output can be set positive, negative, or isolated. The adjustable feedback pin references 1.244 V. ## Through-hole package and thermal handling The TO-220-5 package is a through-hole part with a metal tab. The junction temperature range is -40°C to 125°C. ## Sourcing and lifecycle The LT1082IT#PBF is listed as Active in production and ROHS3 compliant. There is no last-time-buy notice or NRND flag on this part, so it is safe to qualify for new designs. No direct second-source alternate is listed by the manufacturer, but the LT1373IS8#PBF (surface-mount, 1.5 A switch, 250 kHz) covers a similar topology set if your board can accommodate an SOIC-8 package and a higher switching frequency.","metaTitle":"LT1082IT#PBF Step-Up/Step-Down Regulator, 850 mA Switch","metaDescription":"LT1082IT#PBF from Analog Devices is an adjustable switching regulator supporting buck, boost, flyback, and forward topologies.","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, Flyback, Forward Converter","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"TO-220-5","lifecycle_stage":"eol_hot","Current - Output":"850mA (Switch)","Number of Outputs":"1","Output Configuration":"Positive or Negative, Isolation Capable","Frequency - Switching":"12kHz ~ 60kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"75V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"100V (Switch)","Supplier Device Package":"TO-220-5","Voltage - Output (Min/Fixed)":"1.244V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.29","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$16.29000","currency":"USD"},{"qty":10,"price":"$14.97500","currency":"USD"},{"qty":25,"price":"$14.35440","currency":"USD"},{"qty":100,"price":"$12.64750","currency":"USD"},{"qty":250,"price":"$12.02676","currency":"USD"},{"qty":500,"price":"$11.25084","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/1082fas.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LT1082IT#PBF active or obsolete?","answer":"No end-of-life notice has been issued; it is safe for new designs."},{"question":"What is the maximum output current of LT1082IT#PBF?","answer":"The integrated switch is rated for 850 mA peak.
