The 3 MHz switching frequency lets you use a small inductor — typically 1 µH to 2.2 µH — which shrinks the total solution footprint on a 6-SON (1.45x1) package. ## 3 MHz switching shrinks the inductor At 3 MHz, the converter operates well above the AM band, so the inductor value and output capacitor can be roughly one-third the size of a 1 MHz design. The fixed 3V output eliminates the feedback resistor divider, saving two external resistors and one feedback-node noise source. The synchronous rectifier improves efficiency at light load, but at 125°C junction the 500 mA output may need derating depending on PCB copper area — the 6-SON (1.45x1) package has a small thermal pad, so a 4-layer board with thermal vias is recommended for full current at high ambient. ## Active production, sourced per RFQ","metaTitle":"TPS62233DRYR 3V 500mA Step-Down Buck Converter","metaDescription":"Texas Instruments TPS62233DRYR: 3V fixed output, 500mA step-down buck converter, 2.05V-6V input, 3MHz switching, -40°C to 125°C, 6-SON (1.45x1).","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":"6-UFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS62233","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)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5000","priceTiers":[{"qty":1,"price":"$1.50000","currency":"USD"},{"qty":10,"price":"$1.33800","currency":"USD"},{"qty":25,"price":"$1.27040","currency":"USD"},{"qty":100,"price":"$1.04350","currency":"USD"},{"qty":250,"price":"$0.97540","currency":"USD"},{"qty":500,"price":"$0.86200","currency":"USD"},{"qty":1000,"price":"$0.68052","currency":"USD"},{"qty":2500,"price":"$0.64200","currency":"USD"},{"qty":5000,"price":"$0.64200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d4bd0b976f6974a22ac776d1e67c96a3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62233DRYR/alternatives.json"},"ai":{"faq":[{"question":"When sourcing TPS62233DRYR, what's the closest functional second-source — LM53625LQURNLRQ1?","answer":"The LM53625LQURNLRQ1 is an automotive-grade (AEC-Q100) buck converter with 2.5A output and a wider input range (3.9V-36V), but it is not a pin-compatible or direct functional replacement for the TPS62233DRYR.
