Switching losses scale with frequency, so efficiency at light loads is lower than a 1 MHz regulator. The synchronous rectifier helps, but the thermal budget in the 8-DSBGA package still needs the copper pour on the PCB to pull heat out. ## Output current and voltage range — sizing the rail Rated 500 mA continuous output, adjustable from 0.6 V up to 5.4 V. The 500 mA ceiling means it fits a local point-of-load rail for a sensor, RF transceiver, or low-power MCU — not a system-level power bus. The 8-pin DSBGA is a wafer-level chip-scale package. The solder balls are under the die, so the PCB land pattern must match TI's recommended layout exactly — no scope for hand-routing between pads.","metaTitle":"TPS62320YZDR Buck Regulator, 3 MHz, 500 mA, Obsolete","metaDescription":"Texas Instruments TPS62320YZDR is a 3 MHz step-down buck regulator, 500 mA output, adjustable from 0.6V to 5.4V.","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)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","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)":"5.4V","Supplier Device Package":"8-DSBGA","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/664e85230a0dcba807f15e368bfeea9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62320YZDR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62320YZDR obsolete?","answer":"Yes, Texas Instruments lists the TPS62320YZDR as Obsolete.
