That pad must be soldered to a copper plane on the PCB to carry the heat from the 3A output at high input-to-output differentials. The operating junction range is 0°C to 125°C, so the design needs to keep the junction below the upper limit under full load, especially at elevated ambient temperatures. The supplier device package is the same 16-TSSOP-EP; the Tube shipment format is fine for prototype and low-volume builds. ## Lifecycle and compliance — no obsolescence concern The LT3430EFE#PBF is listed as Active on the manufacturer's lifecycle status and is ROHS3 compliant. ## Cross-shop memo — LT3435EFE#PBF vs this part The closest peer in the same family is the LT3435EFE#PBF. Both are positive-output, adjustable Buck regulators in the same 16-TSSOP-EP package with a 3A output rating and no synchronous rectifier. The key difference is switching frequency: the LT3430EFE#PBF runs at 200kHz, while the LT3435EFE#PBF runs at 500kHz. The higher frequency of the LT3435 shrinks the inductor and capacitor values, saving board space, but increases switching losses. If the design can tolerate a larger inductor and wants lower switching losses, the LT3430EFE#PBF is the better fit. If board area is tight, the LT3435EFE#PBF is the alternative to evaluate.","metaTitle":"Analog Devices LT3430EFE#PBF Step-Down Regulator, 3A","metaDescription":"LT3430EFE#PBF is an active, ROHS3-compliant step-down DC-DC regulator from Analog Devices. 60V input, adjustable output to 57.6V, 3A, 200kHz switching.","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, SEPIC","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"200kHz","Operating Temperature":"0°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"60V","Voltage - Input (Min)":"5.5V","Voltage - Output (Max)":"57.6V","Supplier Device Package":"16-TSSOP-EP","Voltage - Output (Min/Fixed)":"1.219V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.93","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.93000","currency":"USD"},{"qty":10,"price":"$12.80700","currency":"USD"},{"qty":95,"price":"$10.81621","currency":"USD"},{"qty":285,"price":"$10.28533","currency":"USD"},{"qty":570,"price":"$9.62177","currency":"USD"},{"qty":1045,"price":"$8.82548","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/34301fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent or replacement for LT3430EFE#PBF?","answer":"The closest functional alternative within the same family is the LT3435EFE#PBF.
