The output is factory-set to 1.8 V (fixed), so no external feedback divider is needed — the BOM count stays low. Synchronous rectification (internal low-side FET) eliminates the external Schottky diode and improves efficiency above 85% across the load range. ## Obsolete — sourcing and replacement planning For new designs, TI's TPS62313 family shares the same pinout and 8-DSBGA footprint across output voltage options (0.8 V to 1.8 V fixed), but a direct pin-compatible replacement with identical 500 mA / 3 MHz rating is not formally cross-referenced. Evaluate the TPS62313YZDR's 1.8 V fixed output against the TPS62313 series voltage variants if the board layout and inductor can accommodate a slightly different output set-point. ## Package and layout — 8-DSBGA realities The 3 MHz switching edge rate means the input capacitor (4.7 µF ceramic, 0805 or smaller) must sit within 2 mm of the VIN ball to keep switching noise below 50 mVpp.","metaTitle":"TPS62313YZDR 500mA 3MHz Buck Converter, Obsolete","metaDescription":"Texas Instruments TPS62313YZDR step-down buck converter, 2.7V-6V input, 1.8V fixed output, 500mA, 3MHz switching, 8-DSBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"8-UFBGA, DSBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS623","Output Configuration":"Positive","Frequency - Switching":"3MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"-","Supplier Device Package":"8-DSBGA","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/664e85230a0dcba807f15e368bfeea9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62313YZDR/alternatives.json"},"ai":{"faq":[{"question":"What is the direct replacement for the TPS62313YZDR by Texas Instruments?","answer":"No direct pin-compatible replacement with identical 500 mA / 3 MHz / 1.8 V fixed output is formally cross-referenced by TI. The TPS62313 family shares the same 8-DSBGA footprint and pinout across output voltage options (0.8 V to 1.8 V fixed), so a different voltage variant may fit if the output set-point can be adjusted.
