The adjustable output voltage range spans 0.6V minimum to 17.82V maximum, making it suitable for generating intermediate bus rails or point-of-load supplies from 5V, 12V, or 18V sources. ## External Schottky diode required — no synchronous rectifier This regulator uses an asynchronous buck topology — the internal switch handles the high-side duty cycle, but an external Schottky catch diode is required on the SW pin for the low-side freewheeling path. The diode's forward voltage and thermal rating must be matched to the 8A output current and the switching frequency; a 40V, 10A-rated Schottky in a D2PAK or similar package is typical for full-load operation. The absence of a synchronous rectifier means the efficiency curve peaks at moderate loads and drops at light loads due to the diode's forward drop. For designs prioritising efficiency below 1A, a synchronous alternative may be preferred, but the LTC3608's simplicity and lower cost in the power stage are advantages for fixed-load applications. ## Active production with ROHS3 compliance The part is offered in Tape & Reel (TR) and Cut Tape (CT) packaging options. The TR suffix indicates full reel quantities suitable for production pick-and-place, while CT availability supports prototyping and low-volume builds without committing to a full reel.","metaTitle":"LTC3608EWKG#TRPBF Buck Regulator, 8A, 4-18V Input","metaDescription":"Analog Devices LTC3608EWKG#TRPBF step-down buck regulator, 8A output, 4V to 18V input range, adjustable output from 0.6V, -40°C to 125°C, 52-QFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"52-VFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"8A","Number of Outputs":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"18V","Voltage - Input (Min)":"4V","Voltage - Output (Max)":"17.82V","Supplier Device Package":"52-QFN-Multipad (7x8)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$18.98000","currency":"USD"},{"qty":10,"price":"$17.44600","currency":"USD"},{"qty":25,"price":"$16.72320","currency":"USD"},{"qty":100,"price":"$14.73440","currency":"USD"},{"qty":250,"price":"$14.01124","currency":"USD"},{"qty":500,"price":"$13.10728","currency":"USD"},{"qty":2000,"price":"$11.57056","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to LTC3608EWKG#TRPBF?","answer":"The LT3680EMSE#TRPBF is a lower-current sibling in the same buck family, but it delivers only 3.5A output versus the LTC3608's 8A.
