The 2.25 MHz switching frequency lets you use small 1 µH to 2.2 µH inductors and small ceramic caps, keeping the total solution footprint tight. ## Input range and output adjust — what the numbers mean Minimum input is 2.5 V, maximum is 5.5 V. The output is adjustable from a 0.85 V minimum up to 5.5 V via an external resistor divider. The 0.85 V floor is low enough to power 1.2 V or 1.8 V logic cores directly, which is common in wireless SoCs and FPGAs. The output voltage is set by the ratio of two resistors — no trim pot, no factory programming. The 600 mA output is the continuous rating. ## Package and temperature — SOT-23-5, industrial grade The TPS62561DDCR comes in a thin SOT-23-5 package (SOT-23-THIN, also called TSOT-23-5). Five pins — input, output, ground, enable, and feedback. The thin profile (about 1 mm) is useful for low-profile enclosures. That covers outdoor telecom gear, factory floor sensors, and automotive cabin applications (non-engine bay). The part is surface-mount and reflow-solderable; standard MSL level for this package family is typically 1, but confirm the bake requirement on the reel label if it has been sitting. The base product number is TPS62561, and this DDC suffix is the standard SOT-23-5 variant.","metaTitle":"TPS62561DDCR Buck Regulator, 2.5V-5.5V Input, 600mA, 2.25MHz","metaDescription":"Texas Instruments TPS62561DDCR step-down buck converter, 2.5V to 5.5V input, 600mA output, 2.25MHz switching, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"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":"SOT-23-5 Thin, TSOT-23-5","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"600mA","Number of Outputs":"1","Base Product Number":"TPS62561","Output Configuration":"Positive","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"SOT-23-THIN","Voltage - Output (Min/Fixed)":"0.85V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e35da18182bac5b2dfc17ae8265721a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62561DDCR/alternatives.json"},"ai":{"faq":[{"question":"What is the switching frequency and efficiency of TPS62561DDCR?","answer":"The switching frequency is 2.25 MHz.
