Synchronous rectification improves efficiency at lower output voltages compared to a diode-based boost, which matters when the output is close to the input voltage. ## Voltage rails and load budget The 1.8 A switch current is the peak current the internal NMOS switch can handle. For a given output voltage and load, the input current will be higher than the output current by the boost ratio divided by efficiency. A 3.3 V output at 500 mA from a 1.5 V input, for example, draws roughly 1.2 A from the input — leaving headroom below the 1.8 A switch limit. The datasheet layout recommendation calls for multiple vias under the pad to a ground plane.","metaTitle":"TPS61029DRCR Boost Converter, 1.8A Switch, 0.9V-5.5V","metaDescription":"Texas Instruments TPS61029DRCR step-up boost converter. 600 kHz switching, 1.8 A switch, adjustable output 1.8 V to 5.5 V. 10-VSON package.","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-Up","Topology":"Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1.8A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61029","Output Configuration":"Positive","Frequency - Switching":"600kHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"0.9V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"10-VSON (3x3)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/107d25c07592cffa29d868ad3be6fd9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61029DRCR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61029DRCR compatible with 3.3 V input?","answer":"Yes.
