The 3 MHz switching frequency lets the designer use a small inductor and output capacitor, shrinking the total solution footprint for space-constrained boards. At 3 MHz the switching period is about 330 ns, so the inductor ripple current stays manageable with values in the 1 µH to 2.2 µH range. That keeps the inductor physically small — typically a 2.5 mm × 2.0 mm shielded type — and the output capacitor in the 10 µF to 22 µF ceramic class. The synchronous rectifier eliminates the external Schottky catch diode, saving one component and one placement step. ## Package and thermal: 10-VSON with exposed pad The 10-VSON (3 mm × 3 mm) package has an exposed thermal pad on the bottom. The datasheet recommends a 2.6 mm × 2.6 mm copper land on the PCB with at least four thermal vias to the ground plane. Without that pad soldered to a copper pour, the junction-to-ambient thermal resistance rises and the 500 mA output at high ambient temperature may push the die past the 85°C operating limit.","metaTitle":"TPS62301DRCRG4 Buck Converter, 3 MHz, 500 mA","metaDescription":"Texas Instruments TPS62301DRCRG4 step-down buck converter, 3 MHz switching frequency, 500 mA output, fixed 1.5 V, 10-VSON package.","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":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS62301","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)":"1.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4029e7575af689f25c35ced969df2e40.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does TPS62301DRCRG4 need an external inductor?","answer":"Yes, like any non-module buck converter, it requires an external inductor and output capacitor.
