That frequency also pushes the fundamental switching noise above the AM band, which simplifies filtering in RF-adjacent designs. ## Input range and output — which rails it fits With a 3V minimum input, this part runs from a single lithium-ion cell or a 3.3V rail, and the 17V maximum covers 12V intermediate buses with margin. The fixed 5V output is set internally — no external feedback divider, so the BOM count stays low. The 2A continuous rating suits point-of-load rails for sensors, small FPGAs, or auxiliary supplies in industrial control. ## 16-VQFN package — rework and board layout The 16-VFQFN with exposed pad (3x3 mm body) is a compact package that demands a hot-air rework station for removal — don't try it with a soldering iron. The 0.50 mm pitch is fine enough that a solder bridge between adjacent pins is hard to see without magnification, so inspect under a microscope after reflow.","metaTitle":"TPS62143RGTT Texas Instruments Buck Converter, 2A, 2.5MHz","metaDescription":"Texas Instruments TPS62143RGTT step-down converter, 2A output, 2.5MHz switching, 3V to 17V input, 5V fixed output, 16-VQFN package, active lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"DCS-Control™","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Base Product Number":"TPS62143","Output Configuration":"Positive","Frequency - Switching":"2.5MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"17V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"-","Supplier Device Package":"16-VQFN (3x3)","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c3ebb36f12f6aeb1b7b795250eb44d53.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62143RGTT/alternatives.json"},"ai":{"faq":[{"question":"Does TPS62143RGTT have a pin-compatible substitute?","answer":"The TPS62143 is part of a family with different fixed output voltages (TPS62140 = 1.8V, TPS62141 = 3.3V, TPS62142 = adjustable), but those are different output options, not drop-in replacements for the 5V fixed version."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62143RGTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62143RGTT when reusing this data.
