At that frequency the inductor value drops into the sub-2.2 µH range, which lets you use a small 0805 or 0603 footprint coil — the whole power stage fits in roughly the same board area as the 10-VSON package itself. Input range spans 2.7 V to 6 V, covering a single-cell Li-ion battery (3.0 V to 4.2 V) or a regulated 5 V bus. The output is fixed at 1.8 V, so no feedback divider resistors are needed — one less pair of components and one less noise injection path. ## Synchronous rectification saves the Schottky The internal synchronous rectifier eliminates the external catch diode that a non-synchronous buck would need. That cuts BOM count and removes the diode's forward-voltage loss, which matters most at light loads where the diode would otherwise dominate efficiency. The base product number TPS62303 covers multiple output-voltage variants in the same package, so if your rail voltage changes, the PCB layout stays the same.","metaTitle":"TPS62303DRCR Buck Regulator 3 MHz 500 mA 10-VSON","metaDescription":"Texas Instruments TPS62303DRCR synchronous step-down buck regulator: 2.7 V to 6 V input, fixed 1.8 V output, 500 mA, 3 MHz switching, industrial temp -40°C to","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":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS62303","Output Configuration":"Positive","Frequency - Switching":"3MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"-","Supplier Device Package":"10-VSON (3x3)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8500","priceTiers":[{"qty":1,"price":"$1.85000","currency":"USD"},{"qty":10,"price":"$1.66000","currency":"USD"},{"qty":25,"price":"$1.56600","currency":"USD"},{"qty":100,"price":"$1.33440","currency":"USD"},{"qty":250,"price":"$1.25292","currency":"USD"},{"qty":500,"price":"$1.09630","currency":"USD"},{"qty":1000,"price":"$0.90837","currency":"USD"},{"qty":3000,"price":"$0.88650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4029e7575af689f25c35ced969df2e40.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62303DRCR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS62303DRCR be replaced by TPS62303DRCRG4?","answer":"The TPS62303DRCRG4 is the same base device (TPS62303) with a different ordering code suffix.
