The synchronous rectifier keeps the efficiency curve competitive across the load range. The 18 V input ceiling covers 12 V and 15 V rails cleanly; for 24 V industrial buses a pre-regulator or a higher-voltage part is needed.","metaTitle":"TPS65288RHAR Triple Buck Regulator, 3A/2A, 4.5-18V Input","metaDescription":"Texas Instruments TPS65288RHAR triple-output step-down regulator. 3A and 2A rails, 300kHz-2.2MHz switching, 40-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A, 2A","Number of Outputs":"3","Base Product Number":"TPS65288","Output Configuration":"Positive","Frequency - Switching":"300kHz ~ 2.2MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"18V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"17V","Supplier Device Package":"40-VQFN (6x6)","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0360","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2cefa266879a8d6b9a81bafd3bfabaa9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65288RHAR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS65288RHAR be used for 12V to 3.3V conversion?","answer":"Yes. The 4.5 V to 18 V input range covers 12 V rails, and the adjustable output can be set to 3.3 V using the feedback resistor divider. The 3 A and 2 A channels provide ample headroom for typical 3.3 V loads."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65288RHAR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65288RHAR when reusing this data.
