It delivers a programmable output at 400 mA continuous current, with a 2.25 MHz switching frequency that allows small external inductors and capacitors. Output is programmable via external resistors, with fixed options at 2.5V and 3.3V. ## Output current and switching frequency trade-offs At 400 mA output, the 2.25 MHz switching frequency keeps the inductor value in the 1 µH to 4.7 µH range, saving board area compared to lower-frequency parts. The trade-off is higher switching losses at light loads — expect efficiency to drop below 10 mA output. The programmable output covers 2.5V and 3.3V fixed options, but the part does not support a 1.2V output directly — the minimum fixed voltage is 2.5V. For sub-2V rails, an adjustable version or a different regulator is needed. Input and output capacitors should be placed within 2 mm of the respective pins to minimize loop inductance at 2.25 MHz. The inductor should be a shielded type rated for at least 500 mA saturation current.","metaTitle":"TPS62273DRVT Buck Converter 400mA 2.25MHz 6-WSON","metaDescription":"Texas Instruments TPS62273DRVT step-down buck regulator, 2V to 6V input, 400 mA output, 2.25 MHz switching, -40°C to 85°C, 6-WSON (2x2) package.","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":"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":"TPS62273","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)":"2.5V, 3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6400","priceTiers":[{"qty":1,"price":"$1.64000","currency":"USD"},{"qty":10,"price":"$1.46900","currency":"USD"},{"qty":25,"price":"$1.38600","currency":"USD"},{"qty":100,"price":"$1.18080","currency":"USD"},{"qty":250,"price":"$1.10876","currency":"USD"},{"qty":500,"price":"$0.97016","currency":"USD"},{"qty":1250,"price":"$0.80385","currency":"USD"},{"qty":2500,"price":"$0.78450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5309ef589e2b37d95314812f0269dbc2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62273DRVT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62273DRVT a direct replacement for TPS62273DRVR?","answer":"The base product number is TPS62273 for both.
