Switching frequency is programmable from 1.8MHz to 4MHz, allowing the PCB layout engineer to select inductor values in the 0.47µH to 2.2µH range and keep the ripple within the output capacitor's ESR budget. ## AEC-Q100 Grade and Temperature Range Lifecycle status is Active. The part is ROHS3 compliant. ## Package and Mounting Checklist Supplied in a 14-VQFN-HR package (2.3mm x 2.7mm body) with wettable flanks for automated optical inspection (AOI) after reflow. The exposed thermal pad must be connected to the ground plane with a thermal via array to keep the junction temperature below the 125°C limit under full load. The base product number is TPS62442.","metaTitle":"TPS62442QWRQRRQ1 Dual Buck Regulator AEC-Q100 Automotive","metaDescription":"Texas Instruments TPS62442QWRQRRQ1 dual-channel step-down buck regulator, AEC-Q100 qualified, 2.75-6V input, adjustable output, 1.8-4MHz switching.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Grade":"Automotive","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount, Wettable Flank","Qualification":"AEC-Q100","Package / Case":"14-VFQFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1A, 2A, 2A, 3A","Number of Outputs":"2","Base Product Number":"TPS62442","Output Configuration":"Positive","Frequency - Switching":"1.8MHz ~ 4MHz","Operating Temperature":"-40°C ~ 125°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.75V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"14-VQFN-HR (2.3x2.7)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6800","priceTiers":[{"qty":1,"price":"$2.68000","currency":"USD"},{"qty":10,"price":"$2.41100","currency":"USD"},{"qty":25,"price":"$2.27920","currency":"USD"},{"qty":100,"price":"$1.97540","currency":"USD"},{"qty":250,"price":"$1.87412","currency":"USD"},{"qty":500,"price":"$1.68162","currency":"USD"},{"qty":1000,"price":"$1.41824","currency":"USD"},{"qty":3000,"price":"$1.34733","currency":"USD"},{"qty":6000,"price":"$1.29668","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4b0e947f38167c7ee1453771832971e0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62442QWRQRRQ1/alternatives.json"},"ai":{"faq":[{"question":"Can TPS62442QWRQRRQ1 be used in battery-powered applications?","answer":"Yes.
