This part is built for automotive infotainment, cluster, and ADAS camera modules that need a clean bipolar supply from a single battery rail — think op-amp rails, LCD bias, or sensor front-ends. ## What the 1.7 A switch rating means for your load budget The 1.7 A switch current rating is the peak current the internal power switch can handle — not the output current. In a boost converter, output current is lower than switch current by the duty-cycle factor. For a 5 V output from a 3.3 V input, expect roughly 1 A available on the positive rail before the switch current limit is reached. The negative buck-boost rail will deliver less, typically 0.5 A to 0.7 A depending on input-to-output ratio. Compared to single-output automotive bucks like the LMR33630APCQRNXRQ1 (3 A, synchronous) or LMS3655MQURNLRQ1 (5.5 A, non-synchronous), the TPS65131TRGERQ1 trades raw current for the ability to produce a negative rail. If your BOM only needs a positive buck, those peers are simpler and more efficient. If you need both +V and -V from one IC, the TPS65131TRGERQ1 is the only AEC-Q100 option in this comparison. ## Active production — sourcing and lifecycle posture Store the reels in a dry cabinet below 30°C / 60% RH; the VQFN is moisture-sensitive per JEDEC level 3. ## Temperature grade and application environment If the application sees sustained junction temperatures above 105°C — for example, near an exhaust manifold or in a transmission controller — the LMS3655MQURNLRQ1 (rated to 150°C TJ) is a better fit, though it is single-output buck only. The non-synchronous architecture means an external Schottky diode is required for each output. The 1.38 MHz switching frequency is fixed — no frequency synchronization to an external clock.","metaTitle":"TPS65131TRGERQ1 Automotive Dual-Rail Boost/Buck-Boost","metaDescription":"Texas Instruments TPS65131TRGERQ1 — automotive AEC-Q100 dual-output adjustable regulator, boost & buck-boost, 1.38MHz, 1.7A switch, -40°C to 105°C, 24-VQFN.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","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":"1.7A (Switch)","Number of Outputs":"2","Base Product Number":"TPS65131","Output Configuration":"Positive and Negative (Dual Rail)","Frequency - Switching":"1.38MHz","Operating Temperature":"-40°C~105°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":"$3.4900","priceTiers":[{"qty":1,"price":"$3.49000","currency":"USD"},{"qty":10,"price":"$3.13300","currency":"USD"},{"qty":25,"price":"$2.96200","currency":"USD"},{"qty":100,"price":"$2.56720","currency":"USD"},{"qty":250,"price":"$2.43556","currency":"USD"},{"qty":500,"price":"$2.18542","currency":"USD"},{"qty":1000,"price":"$1.86300","currency":"USD"},{"qty":3000,"price":"$1.86300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/270ed237063643c09fe005b350752a01.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65131TRGERQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS65131TRGERQ1 automotive qualified?","answer":"Yes, it is listed under the Automotive, AEC-Q100 series, meaning it has passed the AEC-Q100 stress tests for automotive-grade reliability."},{"question":"Can TPS65131TRGERQ1 output both positive and negative voltages?","answer":"Yes, it provides two adjustable outputs: a positive rail from 3.2 V to 15 V and a negative rail from -2 V to -15 V.
