You will not find it at DigiKey or Mouser on a standard lead time. ## 500 mA, 3 MHz, fixed 1.5 V — the fit decision This is a synchronous step-down (buck) regulator with a fixed 1.5 V output and a positive output configuration. It delivers up to 500 mA continuous from an input range of 2.7 V to 6 V. But that high frequency also means the switching edges are fast — layout is critical to keep the switching loop tight and avoid EMI issues. The integrated synchronous rectifier boosts efficiency, especially at lower output voltages, so you don't need an external Schottky diode. ## Industrial temperature range — where it works It is not qualified to AEC-Q100, so it is not a direct fit for automotive under-hood or cabin applications without additional qualification work.","metaTitle":"TPS62321YZDT TI Step-Down Regulator, 500 mA, 3 MHz, 8-DSBGA","metaDescription":"Texas Instruments TPS62321YZDT synchronous buck regulator, 500 mA output, 3 MHz switching, 1.5 V fixed output.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"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)":"1.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/664e85230a0dcba807f15e368bfeea9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62321YZDT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62321YZDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62321YZDT when reusing this data.
