This is not a hand-solderable part; it requires a solder-paste stencil and reflow oven. The footprint is essentially the die size, so the PCB land pattern must match TI's recommended layout exactly to avoid solder bridging. For prototyping or rework, you will need a hot-air rework station with a fine nozzle and a steady hand. The DSBGA package also demands careful handling — moisture sensitivity level (MSL) is typically 1 for this family, but verify the bake requirements if the part has been exposed to ambient humidity. No official successor is listed on the product record. If you are starting a new design, look at TI's current TPS623xx family for pin-compatible or functionally equivalent alternatives.","metaTitle":"TPS62321YEDT Texas Instruments Step-Down Regulator, 3 MHz","metaDescription":"TPS62321YEDT from Texas Instruments is a 3 MHz fixed-output buck regulator rated 500 mA in an 8-DSBGA package.","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":"$1.9300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/664e85230a0dcba807f15e368bfeea9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62321YEDT/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS62321YEDT?","answer":"No official replacement is listed on the product record.
