It integrates seven output rails from a single 2.2V to 5.5V input supply, covering the VDDQ, VTT, and VREF rails a DDR memory subsystem needs without separate LDOs or switchers for each termination voltage. ## Seven outputs — what each rail handles Seven regulated outputs let the TPS6521845RSLT power the core memory voltage (VDDQ), the tracking termination rail (VTT), and the reference voltage (VREF) simultaneously, plus additional system rails for the memory controller or I/O buffers. The multiple-output architecture collapses a discrete power-tree into one 48-VFQFN package, saving board area and reducing BOM count on a DDR memory interface. ## Industrial temperature range — where it fits The 105°C ceiling gives headroom above the 85°C commercial limit, so the part stays within derating curves when the enclosure temperature climbs under full load. ## Package and mounting — layout notes for the 48-VQFN Housed in a 48-VFQFN with exposed pad (6x6 mm body), the TPS6521845RSLT requires a thermal land pattern on the PCB to pull heat from the die. The 0.5 mm pitch QFN needs a solder-paste stencil aperture that balances solder joint volume against the risk of bridging on the fine-pitch perimeter pads.","metaTitle":"TPS6521845RSLT DDR Termination PMIC, 7 Outputs, 2.2V-5.5V","metaDescription":"Texas Instruments TPS6521845RSLT PMIC for DDR/DDR2/DDR3 termination. 7 outputs, 2.2V-5.5V input, -40°C to 105°C, 48-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)","Applications":"Converter, DDR, DDR2, DDR3","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN Exposed Pad","Product Status":"Active","Voltage - Input":"2.2V ~ 5.5V","lifecycle_stage":"eol_hot","Voltage - Output":"Multiple","Number of Outputs":"7","Base Product Number":"TPS6521845","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"48-VQFN (6x6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fdb22883172b60c59ec40cdf345e3291.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6521845RSLT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS6521845RSLT compatible with DDR2 and DDR3 memory?","answer":"Yes.
