The switching frequency can be set anywhere from 200 kHz to 2 MHz via an external resistor. Running at 2 MHz shrinks the inductor to a 1 µH to 2.2 µH footprint, ideal for space-constrained 24-VFQFN layouts; dropping to 200 kHz reduces switching losses for higher efficiency in thermally sensitive enclosures.","metaTitle":"TPS65283RGER Step-Down Regulator, 3.5A/2.5A Dual Output","metaDescription":"Texas Instruments TPS65283RGER dual buck regulator, 4.5V-18V input, adjustable output, 3.5A and 2.5A channels, 200kHz-2MHz switching, -40°C to 125°C.","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":"Tape & Reel (TR)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3.5A, 2.5A","Number of Outputs":"2","Base Product Number":"TPS65283","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"18V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"9V","Supplier Device Package":"24-VQFN (4x4)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3860","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8c94a5bb832ff5529b22ce8e0c332db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65283RGER/alternatives.json"},"ai":{"faq":[{"question":"What are the output current ratings of TPS65283RGER?","answer":"One output is rated 3.5 A and the other is rated 2.5 A, both adjustable from 0.6 V to 9 V."},{"question":"Is TPS65283RGER equivalent to TPS65283?","answer":"TPS65283RGER is a specific packaging variant (Tape & Reel, 24-VFQFN) of the base TPS65283 family.
