The boost output delivers 3.3 V at 1.8 A, while the LDO provides a programmable output from 0.9 V to 3.6 V at 500 mA. This combination saves board space and reduces component count in applications that need both a main power rail and a lower-current secondary rail from a single battery input. ## 500 kHz switching – inductor sizing trade-off The boost converter switches at 500 kHz, a frequency that balances inductor size against efficiency. At this rate, a 4.7 µH to 10 µH inductor typically works for the 1.8 A output, keeping the component height under 2 mm. ## Input range from 0.8 V – single-cell battery ready The 0.8 V minimum input is below the typical UVLO of many boost converters, so it suits low-voltage energy-harvesting or primary-cell designs. It is not qualified for automotive under-hood or extended-temperature industrial beyond 85°C.","metaTitle":"TPS61103RGERG4 Dual-Output Boost + LDO, 500kHz, Obsolete","metaDescription":"Texas Instruments TPS61103RGERG4 dual-output step-up boost + LDO, 500kHz switching, 0.8V-3.3V input, 3.3V/1.8A and 0.9-3.6V/500mA outputs, -40°C to 85°C.","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)","Topology":"Step-Up (Boost) Synchronous (1), Linear (LDO) (1)","w/Sequencer":"No","w/LED Driver":"No","w/Supervisor":"No","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"0.8V ~ 3.3V","Number of Outputs":"2","Base Product Number":"TPS611","Frequency - Switching":"500kHz","Operating Temperature":"-40°C~85°C","Supplier Device Package":"24-VQFN (4x4)","Voltage/Current - Output 1":"3.3V, 1.8A","Voltage/Current - Output 2":"0.9V ~ 3.6V, 500mA","Voltage/Current - Output 3":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c603129158f3030aac28693e1934982a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61103RGERG4/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61103RGERG4 obsolete?","answer":"Yes, the product status is Obsolete.
