The fixed output eliminates the feedback divider network, saving two resistors and one feedback node on the PCB. The 1.25 MHz switching frequency allows the use of small inductors and ceramic output capacitors, keeping the total solution footprint compact for space-constrained designs. ## Synchronous rectifier and efficiency With an integrated synchronous rectifier, the TPS62225DDCT eliminates the external Schottky catch diode, reducing BOM count and improving efficiency at light loads. The single 400 mA output is suited for powering low-voltage digital cores, sensor rails, or I/O supplies in portable and battery-powered equipment. ## Active lifecycle and package The part is ROHS3 compliant.","metaTitle":"TPS62225DDCT Buck Converter 2.2V 400mA TSOT-23-5","metaDescription":"Texas Instruments TPS62225DDCT step-down buck regulator, fixed 2.2 V output, 400 mA, synchronous rectifier, 1.25 MHz switching, TSOT-23-5, active production","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":"SOT-23-5 Thin, TSOT-23-5","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"400mA","Number of Outputs":"1","Base Product Number":"TPS62225","Output Configuration":"Positive","Frequency - Switching":"1.25MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-23-THIN","Voltage - Output (Min/Fixed)":"2.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6400","priceTiers":[{"qty":1,"price":"$1.64000","currency":"USD"},{"qty":10,"price":"$1.46900","currency":"USD"},{"qty":25,"price":"$1.38600","currency":"USD"},{"qty":100,"price":"$1.18080","currency":"USD"},{"qty":250,"price":"$1.10876","currency":"USD"},{"qty":500,"price":"$0.97016","currency":"USD"},{"qty":1250,"price":"$0.80385","currency":"USD"},{"qty":2500,"price":"$0.78450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fdebdac83e1f727df2d6a837b26c191f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62225DDCT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62225DDCT pin-compatible with TPS62225DDCR?","answer":"Both parts share the same base product number TPS62225 and the same TSOT-23-5 package.
