The 32-HTSSOP exposed-pad package pulls heat from the die into the PCB copper plane, which is the difference between a 5 A design that runs cool and one that thermally throttles. ## 5 A per channel — what the current rating means for the BOM Each of the two outputs is rated for 5 A continuous. That is the per-channel current, not a shared total — a 3 A load on channel 1 and a 4 A load on channel 2 both fit within the rating, leaving margin for transient peaks. The synchronous rectifier keeps the dropout low, so the output holds regulation down to near the 0.6 V reference.","metaTitle":"TPS65279DAPR Dual 5A Buck Regulator, 4.5V-18V Input, Active","metaDescription":"Texas Instruments TPS65279DAPR dual 5A step-down buck regulator, adjustable output from 0.6V to 15V, 200kHz-1.6MHz switching, 32-HTSSOP.","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":"32-TSSOP (0.240\\\", 6.10mm Width) Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"5A","Number of Outputs":"2","Base Product Number":"TPS65279","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 1.6MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"18V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"15V","Supplier Device Package":"32-HTSSOP","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7585","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e5408864dda5e2f33d71682ce37df194.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65279DAPR/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum output current per channel of TPS65279DAPR?","answer":"Each of the two outputs is rated for 5 A continuous.
