Switching at 1 MHz lets you use a small inductor — typically 2.2 µH to 4.7 µH — which shrinks the board footprint. The 16-QFN (4x4 mm) package with exposed pad pulls heat into the PCB copper, so the 1.5 A rating holds up to 125°C junction with proper thermal design. The base product number TPS62111 covers a family of fixed-output voltage options, so if a future revision needs a different output voltage, the pin-compatible sibling is available without a layout change. ## Package and mounting — 16-QFN with exposed pad Surface-mount 16-VQFN Exposed Pad, supplier device package 16-QFN (4x4 mm). The 1 MHz switching edge demands a tight loop from input cap to VIN pin to GND plane; keep the input capacitor within 2 mm of the IC.","metaTitle":"TPS62111RSAT 3.3V 1.5A Buck Converter – TI Active 16-QFN","metaDescription":"Texas Instruments TPS62111RSAT step-down regulator: 3.1V–17V input, fixed 3.3V output, 1.5A, 1 MHz, synchronous rectification, –40°C to 125°C, 16-QFN.","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":"Fixed","Mounting Type":"Surface Mount","Package / Case":"16-VQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1.5A","Number of Outputs":"1","Base Product Number":"TPS62111","Output Configuration":"Positive","Frequency - Switching":"1MHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"17V","Voltage - Input (Min)":"3.1V","Voltage - Output (Max)":"-","Supplier Device Package":"16-QFN (4x4)","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8900","priceTiers":[{"qty":1,"price":"$2.89000","currency":"USD"},{"qty":10,"price":"$2.59600","currency":"USD"},{"qty":25,"price":"$2.45440","currency":"USD"},{"qty":100,"price":"$2.12710","currency":"USD"},{"qty":250,"price":"$2.01800","currency":"USD"},{"qty":500,"price":"$1.81072","currency":"USD"},{"qty":1250,"price":"$1.52712","currency":"USD"},{"qty":2500,"price":"$1.45076","currency":"USD"},{"qty":6250,"price":"$1.39622","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6322dd9831e196415747815f04991c08.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62111RSAT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62111RSAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62111RSAT when reusing this data.
