It integrates a synchronous rectifier, so no external Schottky diode is needed — the efficiency curve stays competitive down to light loads. The 8-DSBGA package (0.5 mm ball pitch) is the smallest footprint you'll find for this power class; it's the reason the part was chosen for space-constrained portable designs, but it also means the board layout and reflow profile need to match the DSBGA land pattern exactly. ## Obsolete — the sourcing reality If you are in a redesign window, the 3 MHz switching frequency and 500 mA output with a fixed 1.5 V rail are the parameters a replacement part must match; the DSBGA footprint is the tightest constraint for a pin-compatible swap. The 8-DSBGA package is a wafer-level chip-scale package. The solder balls are the terminals — there are no leads.","metaTitle":"TPS62311YZDR Buck Regulator, 3 MHz, 500 mA, Obsolete","metaDescription":"Texas Instruments TPS62311YZDR step-down buck regulator, 3 MHz switching, 500 mA output, fixed 1.5 V, 8-DSBGA.","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":"$1.3700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/664e85230a0dcba807f15e368bfeea9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62311YZDR/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TPS62311YZDR?","answer":"Submit an RFQ for the quantity you need."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62311YZDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62311YZDR when reusing this data.
