Input range spans 4.5 V to 18 V, covering common 5 V, 9 V, and 12 V rails without a pre-regulator. The two outputs are rated 2 A and 3 A respectively — the asymmetry lets a single IC power a mixed-load board where one rail draws heavier current than the other. ## Switching frequency and thermal envelope Switching frequency is programmable from 300 kHz to 1.4 MHz via an external resistor — a lower frequency cuts switching losses but demands larger magnetics; a higher frequency shrinks the inductor footprint at the cost of higher gate-drive dissipation. The synchronous rectifier improves efficiency at heavy loads by replacing the catch diode with a low-Rds(on) FET. Housed in a 24-TSSOP with exposed pad (HTSSOP, 4.40 mm width).","metaTitle":"TPS65270PWPR Dual Buck Regulator 4.5V-18V 2A/3A","metaDescription":"Texas Instruments TPS65270PWPR dual step-down buck regulator, 4.5V to 18V input, 2A and 3A outputs, adjustable output down to 0.8V, 300kHz-1.4MHz switching","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":"24-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2A, 3A","Number of Outputs":"2","Base Product Number":"TPS65270","Output Configuration":"Positive","Frequency - Switching":"300kHz ~ 1.4MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"18V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"15V","Supplier Device Package":"24-HTSSOP","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0300","priceTiers":[{"qty":1,"price":"$3.03000","currency":"USD"},{"qty":10,"price":"$2.71900","currency":"USD"},{"qty":25,"price":"$2.56520","currency":"USD"},{"qty":100,"price":"$2.18560","currency":"USD"},{"qty":250,"price":"$2.05216","currency":"USD"},{"qty":500,"price":"$1.79564","currency":"USD"},{"qty":1000,"price":"$1.48782","currency":"USD"},{"qty":2000,"price":"$1.45200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1ecc3e7d2d99ac5038323b8c2383bcf7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65270PWPR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS65270PWPR be used for a 5 V to 3.3 V conversion?","answer":"Yes.
