That 25 A rating puts it squarely in the mid-current range for point-of-load converters — enough to power a small FPGA core, a multi-rail communications card, or a bank of DDR memory termination. ## Switching at 600 kHz — inductor and capacitor sizing Fixed 600 kHz switching frequency is a practical middle ground: high enough to keep the inductor below 2 µH (saving board area and DCR losses), yet low enough that switching losses in the integrated MOSFETs don't dominate at 25 A. Expect a 1 µH to 2.2 µH inductor in a typical design, with output capacitors in the 100 µF to 470 µF range depending on transient requirements. The synchronous rectifier helps maintain efficiency above 90% across most of the load range, which matters when the regulator is running near its 25 A ceiling in a confined enclosure. The supplier device package is PG-VIQFN-29; board layout should follow Infineon's recommended footprint for the 5 mm × 6 mm body.","metaTitle":"IR3447AMTRPBFAUMA2 OptiMOS™ Buck Regulator, 25 A, 600 kHz","metaDescription":"Infineon IR3447AMTRPBFAUMA2 OptiMOS™ step-down regulator: 25 A output, 2 V to 17 V input, 600 kHz, adjustable 0.6 V to 7.5 V, -40°C to 125°C, PG-VIQFN-29.","metaKeywords":null},"attributes":{"series":"OptiMOS™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"OptiMOS™","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"29-PowerVFQFN","lifecycle_stage":"eol_hot","Current - Output":"25A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"600kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"17V","Voltage - Input (Min)":"2V","Voltage - Output (Max)":"7.5V","Supplier Device Package":"PG-VIQFN-29","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.06","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.06000","currency":"USD"},{"qty":10,"price":"$4.54300","currency":"USD"},{"qty":25,"price":"$4.29520","currency":"USD"},{"qty":100,"price":"$3.72240","currency":"USD"},{"qty":250,"price":"$3.53148","currency":"USD"},{"qty":500,"price":"$3.16878","currency":"USD"},{"qty":1000,"price":"$2.67246","currency":"USD"},{"qty":4000,"price":"$2.53884","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/35638edd3af4796e4f211cc7b44ea83b.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IR3447AMTRPBFAUMA2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IR3447AMTRPBFAUMA2 when reusing this data.
