That allows inductor values in the 1 µH to 2.2 µH range — small enough for a 0805 or 0603 footprint — while keeping output ripple below 30 mV with a 10 µF ceramic cap. The trade-off is slightly higher switching losses than a 500 kHz part, but for loads under 300 mA the efficiency curve stays above 85% across most of the range. Housed in a 6-WSON (2x2 mm) with an exposed pad, the part relies on the PCB copper pour under the pad for heat sinking. The 0.50 mm pitch WSON demands careful solder-paste stencil design; a 0.125 mm stencil thickness with a 75% aperture reduction on the pad avoids bridging.","metaTitle":"TPS62242DRVRG4 Buck Converter, 300 mA, 2.25 MHz, 6-WSON","metaDescription":"Texas Instruments TPS62242DRVRG4 step-down buck converter, 300 mA output, 2.25 MHz switching, 2-6 V input, 6-WSON (2x2) 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":"-","Package":"Tape & Reel (TR)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"300mA","Number of Outputs":"1","Base Product Number":"TPS62242","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)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ca61cdfbd32e59fb2e26e0404045c164.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62242DRVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the output current of TPS62242DRVRG4?","answer":"The rated continuous output current is 300 mA.
