Output is adjustable from 0.65 V up to 5.5 V, making it a fit for point-of-load regulation in networking, server, and industrial equipment where a high-current, low-voltage rail is needed. Switching frequency is programmable between 400 kHz and 900 kHz, letting you trade efficiency vs inductor size. The 15-FCQFN package (8x4.15 mm) keeps the footprint tight, but the 35 A rating means the thermal design — PCB copper area, airflow, and load profile — is the real constraint, not the silicon. ## No synchronous rectifier — plan the catch diode This regulator does not include a synchronous rectifier. An external Schottky diode is required for the low-side catch diode. The 35 A output and 900 kHz top-end switching frequency demand a diode rated for the input voltage and the full output current. ## Sourcing and lifecycle The MAX20743EPL+T carries an Active product status and is ROHS3 compliant. No end-of-life notice or last-time-buy schedule is in effect. No pin-compatible second source or official replacement is listed — the part is a single-source item, so dual-sourcing requires a separate qualification of an alternate regulator.","metaTitle":"MAX20743EPL+T Buck Regulator, 35A, 15-FCQFN","metaDescription":"Active Maxim Integrated step-down buck regulator, 35 A output, 4.5-16 V input, adjustable output, 15-FCQFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"15-VFQFN, FCQFN","lifecycle_stage":"eol_hot","Current - Output":"35A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"400kHz ~ 900kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"16V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"15-FCQFN (8x4.15)","Voltage - Output (Min/Fixed)":"0.65V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.71","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.71000","currency":"USD"},{"qty":10,"price":"$8.01800","currency":"USD"},{"qty":25,"price":"$7.85120","currency":"USD"},{"qty":50,"price":"$7.82400","currency":"USD"},{"qty":100,"price":"$7.02040","currency":"USD"},{"qty":250,"price":"$6.80816","currency":"USD"},{"qty":500,"price":"$6.47408","currency":"USD"},{"qty":1000,"price":"$6.24834","currency":"USD"},{"qty":2500,"price":"$6.04067","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8bab1e19f3500bf9229538df39738c93.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX20743EPL+T require an external Schottky diode?","answer":"Yes, because the part does not include a synchronous rectifier.
