Switching at 1 MHz allows use of a small external inductor and capacitor, saving board area. Input voltage spans 1.8 V minimum to 6 V maximum. For BOM lines that still require this exact order code, procurement must go through independent distribution — sealed reels with consistent date-codes are the preferred lot condition. Verify the pinout against the target board before selecting an alternate.","metaTitle":"TPS61043DRBRG4 DC-DC Boost Regulator, 1 MHz, 16.9 V Output","metaDescription":"TI TPS61043DRBRG4 step-up boost regulator, 1 MHz switching, 16.9 V output, 60 mA per channel, PWM dimming for backlight.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Regulator","Series":"-","Dimming":"PWM","Package":"Tape & Reel (TR)","Topology":"Step-Up (Boost)","Frequency":"1MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"8-VDFN Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Output":"16.9V","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"TPS610","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"6V","Voltage - Supply (Min)":"1.8V","Supplier Device Package":"8-SON (3x3)","Current - Output / Channel":"60mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/472370e9559390549b04563b6eeae8d5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61043DRBRG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61043DRBRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61043DRBRG4 when reusing this data.
