The 1.8A switch current on each channel supports loads like OLED bias, CCD sensor supplies, or op-amp rails where a split supply is needed without a transformer. ## Output voltage range and switching frequency The positive output adjusts from a 3.2V minimum up to 15V; the negative output adjusts from -2V down to -15V.","metaTitle":"TPS65131RGER Dual Rail Boost/Buck-Boost Regulator - TI","metaDescription":"Texas Instruments TPS65131RGER dual-output adjustable boost/buck-boost regulator. 1.8A switch, 2.7V-5.5V input, ±15V outputs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up, Step-Up/Step-Down","Topology":"Boost, Buck-Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1.8A (Switch)","Number of Outputs":"2","Base Product Number":"TPS65131","Output Configuration":"Positive and Negative (Dual Rail)","Frequency - Switching":"1.38MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"15V, -15V","Supplier Device Package":"24-VQFN (4x4)","Voltage - Output (Min/Fixed)":"3.2V, -2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0000","priceTiers":[{"qty":1,"price":"$3.00000","currency":"USD"},{"qty":10,"price":"$2.69400","currency":"USD"},{"qty":25,"price":"$2.54720","currency":"USD"},{"qty":100,"price":"$2.20760","currency":"USD"},{"qty":250,"price":"$2.09436","currency":"USD"},{"qty":500,"price":"$1.87926","currency":"USD"},{"qty":1000,"price":"$1.60200","currency":"USD"},{"qty":3000,"price":"$1.60200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3862cb6105939e10e645b30789386f30.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65131RGER/alternatives.json"},"ai":{"faq":[{"question":"Can TPS65131RGER output both positive and negative voltages simultaneously?","answer":"Yes — the device has two independent converters: one boost for the positive rail and one buck-boost for the negative rail.
