The 1.25 MHz switching frequency keeps the inductor and output capacitor small — typically a 2.2 µH chip inductor and a 10 µF ceramic cap fit the bill, saving board space in space-constrained designs like wireless modules or sensor nodes. ## Sizing the output for a 1.6V rail The fixed 1.6V output means no external feedback divider; the output voltage is set internally, which simplifies the BOM and removes one potential tolerance stack-up. If your design needs a different voltage, look at the adjustable-output siblings in the TPS6222x family. Texas Instruments has not issued a PCN or end-of-life notice for this part as of the current date. It is offered in both Tape & Reel and Cut Tape options, so prototype quantities and production reels are both available through our sourcing desk. The part comes in a SOT-23-5 Thin package (also called TSOT-23-5), with a 0.95 mm pitch and a body size of roughly 2.9 mm × 1.6 mm. The thin profile (nominal height 0.9 mm) fits into low-profile enclosures.","metaTitle":"TPS62224DDCT Texas Instruments Buck Regulator, 400 mA","metaDescription":"TPS62224DDCT from Texas Instruments: step-down buck regulator, fixed 1.6V output, 400 mA, 1.25 MHz switching, SOT-23-5 Thin package.","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":"TPS62224","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)":"1.6V"}},"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/e0274b1b9bfa903b303a9f5c4630edbb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62224DDCT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62224DDCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62224DDCT when reusing this data.
