The 6-pin SON package (1.45 mm x 1 mm) is the smallest footprint in the TPS6223x family, but the thermal pad is correspondingly small — at 500 mA continuous from a 5 V input, the junction rise above ambient is roughly 40-50°C, so the full 125°C rating is only usable if the board copper area under the pad is generous. ## Input voltage range — the common BOM trap The input range is 2.05 V to 6 V. That 2.05 V minimum lets it run from a single Li-ion cell down to its discharge floor, but the 6 V maximum means it cannot be used on a 12 V or 24 V industrial rail — a mistake that shows up when a designer grabs a 'small buck' without checking the abs-max. If the input bus is above 6 V, step up to the TPS6224x or TPS621xx families. ## 3 MHz switching — inductor selection and light-load behaviour The 3 MHz switching frequency lets the output filter use a 1 µH to 2.2 µH inductor and 10 µF output capacitor, keeping the total solution area under 15 mm². At light loads (below ~50 mA), the part enters pulse-skipping mode to maintain efficiency — the output ripple increases to about 15-20 mV peak-to-peak, which is fine for digital loads but may need post-regulation for noise-sensitive analogue rails. ## Temperature grade and the SON thermal path The 6-SON package has an exposed thermal pad on the bottom — the datasheet recommends a 0.8 mm x 0.8 mm copper land with at least four vias to the ground plane. Without that thermal relief, the effective RθJA climbs above 100°C/W and the 500 mA output derates significantly above 85°C ambient.","metaTitle":"TPS62239DRYR 500 mA Step-Down Buck Converter, 3 MHz, 6-SON","metaDescription":"Texas Instruments TPS62239DRYR step-down DC-DC converter: 500 mA output, 3 MHz switching, 2.05-6 V input, fixed 1 V output, -40 to 125°C.","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); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-UFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS62239","Output Configuration":"Positive","Frequency - Switching":"3MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.05V","Voltage - Output (Max)":"-","Supplier Device Package":"6-SON (1.45x1)","Voltage - Output (Min/Fixed)":"1V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d4bd0b976f6974a22ac776d1e67c96a3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62239DRYR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS62239DRYR be used as a direct replacement for TPS62239DRYT?","answer":"Yes, the TPS62239DRYR and TPS62239DRYT are the same silicon in the same 6-SON package.
