The two controller outputs are labelled simply 'Controller' in the spec — they drive external FETs for the high-current rails. The third output is a fixed 3.3V LDO rated at 10 mA, likely for a standby or always-on supply. The fourth output is a second LDO, though its voltage and current are not specified in the summary data. ## Switching frequency and inductor sizing The switching frequency is programmable from 200 kHz to 1 MHz via an external resistor or sync pin. At the low end you get better efficiency and wider input-to-output step-down ratios, but the inductor grows. At 1 MHz the inductor shrinks to a 2.2 µH or 3.3 µH chip — good for a compact layout — but switching losses in the external FETs rise. If you need AEC-Q100, this part is not the fit. ## Package and hand-solderability Without a thermal via array under the pad, the junction temperature rises quickly above 85°C at full load. Available in Tape & Reel (TR) for production pick-and-place or Cut Tape (CT) for prototyping and small runs. The reel quantity is not listed here, but the CT option lets you buy a handful for a breadboard build without committing to a full reel. It is ROHS3 compliant, so no exemption issues for EU or California market shipments. If you need a drop-in alternative, the BOM is single-sourced to this part number.","metaTitle":"Texas Instruments TPS51222RTVT Quad Buck/LDO PMIC, 4.5-32V","metaDescription":"Texas Instruments TPS51222RTVT quad-output power IC: two buck controllers plus two LDOs. 4.5V-32V input, 200kHz-1MHz switching, 32-WQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Down (Buck) (2), Linear (LDO) (2)","w/Sequencer":"No","w/LED Driver":"No","w/Supervisor":"No","Mounting Type":"Surface Mount","Package / Case":"32-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 32V","Number of Outputs":"4","Frequency - Switching":"200kHz ~ 1MHz","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"32-WQFN (5x5)","Voltage/Current - Output 1":"Controller","Voltage/Current - Output 2":"Controller","Voltage/Current - Output 3":"3.3V, 10mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.79","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.79000","currency":"USD"},{"qty":10,"price":"$7.94200","currency":"USD"},{"qty":25,"price":"$7.57280","currency":"USD"},{"qty":100,"price":"$6.57550","currency":"USD"},{"qty":250,"price":"$6.27996","currency":"USD"},{"qty":500,"price":"$5.72586","currency":"USD"},{"qty":1250,"price":"$5.22750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/30d1bc42978d130e9fd103ab4430785f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the topology of TPS51222RTVT?","answer":"It integrates two step-down (buck) switching controllers and two linear (LDO) regulators in one package — a quad-output power management IC."},{"question":"What package does TPS51222RTVT come in?","answer":"It is offered in a 32-WFQFN exposed-pad package (5x5 mm body, 0.5 mm pitch), also designated as 32-WQFN (5x5)."},{"question":"What compliance documentation does Texas Instruments provide for TPS51222RTVT?","answer":"The part is ROHS3 compliant.
