Output 1 (the buck-boost) delivers 300mA adjustable from 2.5V to 5.5V; Output 2 (the LDO) delivers 320mA over the same voltage range. That covers the common split-rail scenario: a 3.3V core supply plus a 5V sensor or interface rail from one IC. ## 500kHz switching — inductor sizing and ripple The fixed 500kHz switching frequency sets the inductor value and output ripple. At this frequency, a 4.7µH to 10µH shielded inductor keeps the ripple current within 30-40% of the load — a standard selection for the 300mA output. The trade-off: higher frequency would shrink the inductor footprint but push switching losses up; 500kHz is a practical midpoint for efficiency and board area. ## No sequencer, no LED driver — what you don't get This part has no built-in power-up sequencing, no LED driver, and no supervisor. If your design needs sequenced rail enable or a watchdog, you add external logic or a separate supervisor IC. The LDO output is always on when the input is present — the buck-boost enable pin gives you independent control of the first rail.","metaTitle":"TPS61130PW Buck-Boost + LDO, 500kHz, 16-TSSOP","metaDescription":"Texas Instruments TPS61130PW dual-output PMIC: buck-boost (300mA) and LDO (320mA), 1.8V-5.5V input, 500kHz, -40°C to 85°C, 16-TSSOP.","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-Down/Step-Up (Buck/Boost) (1), Linear (LDO) (1)","w/Sequencer":"No","w/LED Driver":"No","w/Supervisor":"No","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"1.8V ~ 5.5V","Number of Outputs":"2","Base Product Number":"TPS61130","Frequency - Switching":"500kHz","Operating Temperature":"-40°C~85°C","Supplier Device Package":"16-TSSOP","Voltage/Current - Output 1":"2.5V ~ 5.5V, 300mA","Voltage/Current - Output 2":"2.5V ~ 5.5V, 320mA","Voltage/Current - Output 3":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.5700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/77e851c519411feb6d487ea2ef8909be.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61130PW/alternatives.json"},"ai":{"faq":[{"question":"Does TPS61130PW require external sequencing?","answer":"No built-in sequencer.
