The fixed 1.5 V output means this part is a direct fit for powering 1.5 V logic rails — DDR memory VTT, low-voltage MCU cores, or sensor supplies — with no external divider resistors. The synchronous rectifier improves efficiency at light loads compared to a diode-based buck, which matters for battery-powered or always-on systems where quiescent current adds up. ## Package and thermal — the exposed pad drives the layout The 10-VSON (3x3) exposed pad package requires a thermal land pattern on the PCB. The 3x3 mm footprint fits two-layer boards with a ground plane under the pad. This is a standard catalog part from Texas Instruments, available through independent distribution channels.","metaTitle":"TPS62042DRCRG4 Step-Down Regulator, 1.2 A, 1.25 MHz","metaDescription":"Texas Instruments TPS62042DRCRG4 is a synchronous step-down buck regulator with 1.2 A output, 2.5 V to 6 V input, fixed 1.5 V output, 1.25 MHz switching, -40°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"1.2A","Number of Outputs":"1","Base Product Number":"TPS62042","Output Configuration":"Positive","Frequency - Switching":"1.25MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"-","Supplier Device Package":"10-VSON (3x3)","Voltage - Output (Min/Fixed)":"1.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62042DRCRG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62042DRCRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62042DRCRG4 when reusing this data.
