It delivers one 3A rail and two 2A rails from a single 4V to 18V input, covering the typical automotive battery range from cold-crank through load-dump. Synchronous rectification is integrated, so no external catch diode is needed. ## Output rails: 3A primary, 2A auxiliary The three outputs are independently programmable from a minimum of 0.68V up to 6.3V. The 3A channel is typically used for the core SoC or processor rail; the two 2A channels handle I/O or memory supplies. Output configuration is positive, and the regulator uses a buck topology. Cut-tape quantities are also available for prototyping.","metaTitle":"TPS65263-1QRHBRQ1 Automotive Triple Buck Converter, AEC-Q100","metaDescription":"Texas Instruments TPS65263-1QRHBRQ1 automotive triple step-down buck converter, AEC-Q100 qualified, 3A/2A/2A outputs, 4V-18V input, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Programmable","Mounting Type":"Surface Mount","Package / Case":"32-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A, 2A, 2A","Number of Outputs":"3","Base Product Number":"TPS65263","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 2.3MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"18V","Voltage - Input (Min)":"4V","Voltage - Output (Max)":"6.3V","Supplier Device Package":"32-VQFN (5x5)","Voltage - Output (Min/Fixed)":"0.68V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aaf7f050f403a1d87909d2329c946f18.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65263-1QRHBRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS65263-1QRHBRQ1 a direct replacement for TPS65263?","answer":"The TPS65263-1QRHBRQ1 is the automotive-qualified (AEC-Q100) variant of the base TPS65263.
