It delivers 3.5 A on one channel and 2.5 A on the other, with both outputs adjustable from 0.8 V up to 15 V from a 4.5 V to 16 V input rail. ROHS3 compliant. At 300 kHz you use a larger inductor but get lower switching losses; at 1.2 MHz the inductor shrinks but the driver losses climb.","metaTitle":"TPS65253RHDR Dual Buck Regulator 3.5A/2.5A Active Texas","metaDescription":"Texas Instruments TPS65253RHDR dual step-down buck regulator, 3.5A and 2.5A outputs, 4.5V-16V input, adjustable output, 28-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"28-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3.5A, 2.5A","Number of Outputs":"2","Base Product Number":"TPS65253","Output Configuration":"Positive","Frequency - Switching":"300kHz ~ 1.2MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"16V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"15V","Supplier Device Package":"28-VQFN (5x5)","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3500","priceTiers":[{"qty":1,"price":"$4.35000","currency":"USD"},{"qty":10,"price":"$3.90800","currency":"USD"},{"qty":25,"price":"$3.69440","currency":"USD"},{"qty":100,"price":"$3.20180","currency":"USD"},{"qty":250,"price":"$3.03760","currency":"USD"},{"qty":500,"price":"$2.72562","currency":"USD"},{"qty":1000,"price":"$2.32350","currency":"USD"},{"qty":3000,"price":"$2.32350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bb4e5a72b333d2bc5afe294cd543440c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65253RHDR/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives for TPS65253RHDR?","answer":"The LM53625LQURNLRQ1 is also single-output, fixed 5 V, 2.5 A, automotive rated.
