The 3 MHz switching frequency lets you use a 1 µH or smaller inductor and a 4.7 µF output cap, shrinking the total solution footprint to about 10 mm². ## 3 MHz switching — why it matters for the BOM At 3 MHz, the switching frequency sits above the AM radio band and well into the region where inductor and capacitor values drop. A typical application needs a 1 µH inductor rated for 1 A saturation and a 4.7 µF ceramic output capacitor — both 0603 or 0402 size. That keeps the passive cost and board area low, but it also pushes the switching losses higher than a 1 MHz part would see. ## 6-DSBGA package — layout gotcha There are no leads to inspect — the bumps reflow directly onto the PCB pads. The small body (about 1.3 mm × 0.9 mm) saves board area, but the exposed bumps mean the board must have a solder-mask-defined pad pattern and a stencil aperture that matches the bump diameter.","metaTitle":"TPS62698YFDR Step-Down Regulator, 3V Fixed Output, 800mA","metaDescription":"TI TPS62698YFDR buck converter: 2.3V-4.8V input, 3V fixed output, 800mA, 3MHz switching, 6-DSBGA, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-XFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"800mA","Number of Outputs":"1","Base Product Number":"TPS62698","Output Configuration":"Positive","Frequency - Switching":"3MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"4.8V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"-","Supplier Device Package":"6-DSBGA","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6960","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d3e7af481b8ba50b8660d2366bdaf547.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62698YFDR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS62698YFDR and TPS62699YFDR?","answer":"The TPS62698YFDR outputs a fixed 3 V.
