That frequency lets you use a small-value inductor — typically in the 2.2 µH to 4.7 µH range — which keeps the overall footprint tight. The 2.25 MHz switching also pushes the fundamental ripple above the AM band, which simplifies filtering in noise-sensitive designs. The output is programmable via external feedback resistors, with a fixed-voltage option at 0.9 V or 1.15 V for the fixed-output variants in the family. ## 400 mA output — load budget and thermal reality Rated for 400 mA continuous output, the TPS62270DRVR fits point-of-load rails for MCU cores, sensor supplies, or wireless module power. The 2.25 MHz switching keeps the inductor small, but the 400 mA ceiling means you need to stay below about 320 mA at 85°C ambient if you want margin — the WSON package's thermal impedance (RθJA around 60°C/W with the exposed pad soldered) will dictate the real-world derating. ## 6-WSON with exposed pad — footprint and thermal handling The 0.65 mm pitch is fine for a standard 2-layer board if you route the output and input caps close.","metaTitle":"TPS62270DRVR Buck Converter, 2.25MHz, 400mA, 6-WSON","metaDescription":"Texas Instruments TPS62270DRVR step-down DC/DC converter: 2V to 6V input, 400mA output, 2.25MHz switching, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"Programmable","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"400mA","Number of Outputs":"1","Base Product Number":"TPS62270","Output Configuration":"Positive","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2V","Voltage - Output (Max)":"-","Supplier Device Package":"6-WSON (2x2)","Voltage - Output (Min/Fixed)":"0.9V, 1.15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6165","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5309ef589e2b37d95314812f0269dbc2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62270DRVR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62270DRVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62270DRVR when reusing this data.
