The DCS-Control topology combines hysteretic and voltage-mode regulation, giving fast transient response with a small output capacitor — useful when the load current jumps between sleep and active states in a battery-powered sensor node or IoT endpoint. ## Programmable output and input range The input range spans 3.3 V to 10 V, which covers single-cell Li-ion (3.6–4.2 V) and 5 V or 9 V rails. Synchronous rectification eliminates the external Schottky diode, keeping the BOM count low for space-constrained designs. The 0.50 mm pitch on the 12-WFDFN requires a 4-layer board for proper fan-out and thermal relief; two-layer breaks out only the peripheral pins. The base product number TPS62745 covers the family; the DSSR suffix denotes the 12-WSON package and tape-and-reel shipping medium.","metaTitle":"TPS62745DSSR Buck Converter, 300 mA, 2.5 MHz, DCS-Control","metaDescription":"Texas Instruments TPS62745DSSR step-down buck converter, 300 mA output, up to 2.5 MHz switching, DCS-Control topology, -40°C to 85°C, 12-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"DCS-Control™","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Programmable","Mounting Type":"Surface Mount","Package / Case":"12-WFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"300mA","Number of Outputs":"1","Base Product Number":"TPS62745","Output Configuration":"Positive","Frequency - Switching":"Up to 2.5MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"10V","Voltage - Input (Min)":"3.3V","Voltage - Output (Max)":"3.3V","Supplier Device Package":"12-WSON (2x3)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/efb1b5ddee921182ec01c37421c0e083.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62745DSSR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS62745DSSR be used for battery-powered applications?","answer":"Yes. The 3.3 V minimum input covers a single-cell Li-ion battery through most of its discharge range. The DCS-Control topology provides fast transient response as the load shifts between active and sleep modes, and the 300 mA output is sized for sensor nodes, wearables, and IoT edge devices."},{"question":"How do I set the output voltage on TPS62745DSSR?","answer":"The output voltage is programmable via an external resistor divider between the feedback pin and ground.
