The trade-off is higher switching losses, but at 300 mA output the efficiency penalty is under 2 % versus a lower-frequency part in the same family. The part comes in a SOT-23-5 Thin (TSOT-23-5) package — 5 pins on 0.95 mm pitch, body 2.9 mm × 1.6 mm. Mounting is surface-mount only. The thin SOT-23 profile suits low-profile assemblies where height above board is constrained to under 1.2 mm.","metaTitle":"TPS62243QDDCRQ1 Automotive Buck Converter, 300 mA, 2.25 MHz","metaDescription":"Texas Instruments TPS62243QDDCRQ1 step-down buck converter, AEC-Q100 qualified, 2 V to 6 V input, fixed 1.8 V output at 300 mA, SOT-23-5 Thin package, -40°C to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SOT-23-5 Thin, TSOT-23-5","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"300mA","Number of Outputs":"1","Base Product Number":"TPS62243","Output Configuration":"Positive","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2V","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-23-THIN","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7005","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d5c2079e030bc593007e0fcc623a98e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62243QDDCRQ1/alternatives.json"},"ai":{"faq":[{"question":"What package is TPS62243QDDCRQ1 available in?","answer":"It is supplied in a SOT-23-5 Thin (TSOT-23-5) package."},{"question":"Does TPS62243QDDCRQ1 require external components?","answer":"Yes, like any buck converter it requires an external inductor and input/output capacitors for operation.
