The 2.25 MHz switching frequency lets you use small 1 µH inductors and 10 µF ceramic output caps, keeping the total solution area under 20 mm² including passives. The 8-WSON (2x2) package with exposed pad pulls heat into the PCB copper — no airflow required at 500 mA load. ## 2.25 MHz switching — inductor and cap sizing At 2.25 MHz the ripple current is low enough that a 1 µH inductor and a 10 µF output capacitor deliver under 30 mV p-p ripple at full load. The DCS-Control™ architecture keeps the loop stable with ceramic output caps — no ESR trick needed. TI lists the TPS62172DSGT as Active.","metaTitle":"TPS62172DSGT Buck Converter, 3.3V Fixed Output, 500 mA","metaDescription":"Texas Instruments TPS62172DSGT step-down buck converter with fixed 3.3V output, 500 mA current, 2.25 MHz switching, 8-WSON package.","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":"8-WFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS62172","Output Configuration":"Positive","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"17V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"-","Supplier Device Package":"8-WSON (2x2)","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d6fec27f39006a215b2ce515120e1e3e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62172DSGT/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS62172DSGT and TPS62173DSGT?","answer":"The TPS62173DSGT is the 5V fixed-output sibling; the TPS62172DSGT is fixed at 3.3V. Both share the same 500 mA rating, 2.25 MHz switching, 8-WSON package, and DCS-Control™ topology. The only parametric difference is the output voltage set point."},{"question":"Is TPS62172DSGT compatible with 5V input?","answer":"Yes. The input range is 3V to 17V, so a 5V rail is well within the operating window. The fixed 3.3V output will regulate cleanly from 5V with the same external component values."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62172DSGT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62172DSGT when reusing this data.
