The boost output handles 1.5V to 5.5V at up to 1.8A, while the LDO provides 0.9V to 3.6V at 500mA — covering the typical dual-rail needs of a battery-powered design: a main system rail and a lower-voltage analog or I/O rail. ## Input range and switching frequency — inductor and cap selection The supply range spans 0.8V to 3.3V, accepting a single Li-ion cell down to its end-of-discharge voltage or two alkaline cells in series. A fixed 500 kHz switching frequency sets the inductor ripple current and output capacitor ripple voltage — a 4.7 µH to 10 µH inductor and a 10 µF to 22 µF ceramic output cap are typical for the boost section, depending on the target output current.","metaTitle":"TPS61100PWG4 Boost + LDO PMIC, 500kHz, 20-TSSOP","metaDescription":"Texas Instruments TPS61100PWG4 dual-output power IC: synchronous boost (1.8A) plus LDO (500mA), 0.8V-3.3V input, -40°C to 85°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":"Tube","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":"20-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"0.8V ~ 3.3V","Number of Outputs":"2","Base Product Number":"TPS61100","Frequency - Switching":"500kHz","Operating Temperature":"-40°C~85°C","Supplier Device Package":"20-TSSOP","Voltage/Current - Output 1":"1.5V ~ 5.5V, 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/TPS61100PWG4/alternatives.json"},"ai":{"faq":[{"question":"Does TPS61100PWG4 come in a tube?","answer":"Yes, the listed packaging form is Tube."},{"question":"What is the difference between TPS61100PWG4 and TPS61100PW?","answer":"The base product number is TPS61100; the suffix 'G4' indicates a lead-free (RoHS-compliant) finish variant.
