This consolidates the power tree for SoCs, FPGAs, and processors that need separate core, I/O, and memory rails. Each output is adjustable from 0.8 V up to the input voltage. ## Switching frequency and thermal envelope Switching frequency is programmable from 300 kHz to 2.2 MHz. Running at the high end shrinks the inductor and output capacitor footprint; dropping to 300 kHz improves efficiency at light load. The trade-off is set by a single resistor. ## Active production — sourcing today","metaTitle":"TPS65257RHAT PMIC – Triple Buck Regulator, 3A/2A, Active","metaDescription":"Texas Instruments TPS65257RHAT triple-output step-down buck regulator. 3A/2A outputs, 4.5V-16V input, adjustable output down to 0.8V.","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-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A, 2A","Number of Outputs":"3","Base Product Number":"TPS65257","Output Configuration":"Positive","Frequency - Switching":"300kHz ~ 2.2MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"16V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"16V","Supplier Device Package":"40-VQFN (6x6)","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8200","priceTiers":[{"qty":1,"price":"$6.82000","currency":"USD"},{"qty":10,"price":"$6.12800","currency":"USD"},{"qty":25,"price":"$5.79320","currency":"USD"},{"qty":100,"price":"$5.02070","currency":"USD"},{"qty":250,"price":"$4.76328","currency":"USD"},{"qty":500,"price":"$4.27406","currency":"USD"},{"qty":1250,"price":"$3.64350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5ccb6c5bcc022e9f59d8d506fb2c9d26.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65257RHAT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65257RHAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65257RHAT when reusing this data.
