Its adjustable output is set via external resistors from a 1.2 V reference up to 33.12 V. ## 500 kHz switching — inductor size vs efficiency The 500 kHz switching frequency is a practical middle ground: it allows the use of small, low-profile inductors (typically 10 µH to 47 µH range) while keeping switching losses moderate. At this frequency, the regulator can maintain good efficiency across a 3.6 V to 36 V input range without resorting to external compensation. The non-synchronous topology means an external Schottky catch diode is required — factor that into the BOM and board area. ## 8-MSOP-EP: thermal management at 1.4 A The 8-MSOP package with exposed pad (MSOP-EP) is the key to getting the full 1.4 A output in a compact footprint. The package is rated for surface-mount assembly and is supplied in Tube (the #PBF suffix indicates ROHS3 compliance). ## Industrial temperature range and operating environment The 36 V input maximum provides headroom for 24 V systems with transients, but for automotive load-dump events above 40 V, external clamping is still needed.","metaTitle":"LT1936EMS8E#PBF Buck Regulator, 1.4A, 500kHz, 8-MSOP-EP","metaDescription":"LT1936EMS8E#PBF step-down regulator: 1.4A output, 500kHz switching, 3.6V to 36V input, adjustable output from 1.2V to 33.12V, -40°C to 85°C, 8-MSOP-EP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"1.4A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"500kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"36V","Voltage - Input (Min)":"3.6V","Voltage - Output (Max)":"33.12V","Supplier Device Package":"8-MSOP-EP","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.96","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.96000","currency":"USD"},{"qty":10,"price":"$7.18800","currency":"USD"},{"qty":25,"price":"$6.85320","currency":"USD"},{"qty":100,"price":"$5.95070","currency":"USD"},{"qty":250,"price":"$5.68328","currency":"USD"},{"qty":500,"price":"$5.18180","currency":"USD"},{"qty":1000,"price":"$4.51318","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/1936fd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for LT1936EMS8E#PBF?","answer":"The LT1936EMS8E#TRPBF is the same die and package in Tape & Reel format — a direct packaging alternate, not a second source.
