That pad needs a solid via array to the ground plane to keep junction temperature under 150°C at full load. The part is surface-mount — rework with a hot-air station is possible if the pad is properly tinned, but the small pitch means a stencil is the reliable production path.","metaTitle":"TPS62442RQRR Dual 3A Buck Regulator - Active, 21-VQFN","metaDescription":"TPS62442RQRR from Texas Instruments: dual 3A/3A step-down buck, 2.25 MHz, adjustable output down to 0.6V, -40°C to 150°C junction.","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":"21-PowerVFQFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A/3A, 3A/2A","Number of Outputs":"2","Output Configuration":"Positive","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.75V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"21-VQFN-HR (3x5)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3800","priceTiers":[{"qty":1,"price":"$2.38000","currency":"USD"},{"qty":10,"price":"$2.14100","currency":"USD"},{"qty":25,"price":"$2.02000","currency":"USD"},{"qty":100,"price":"$1.72100","currency":"USD"},{"qty":250,"price":"$1.61600","currency":"USD"},{"qty":500,"price":"$1.41400","currency":"USD"},{"qty":1000,"price":"$1.17160","currency":"USD"},{"qty":3000,"price":"$1.09080","currency":"USD"},{"qty":6000,"price":"$1.05040","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2801e57ef69695632c2e8d467bb5a099.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62442RQRR/alternatives.json"},"ai":{"faq":[{"question":"What input voltage range does the TPS62442RQRR support?","answer":"It operates from 2.75 V minimum to 6 V maximum input, making it a fit for 3.3 V and 5 V rails common in battery-powered or intermediate-bus designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62442RQRR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62442RQRR when reusing this data.
