It integrates a 200mA switch and synchronous rectifier in a 6-pin SC-70-6 package. ## What the 0.7V minimum input means for your battery selection A 0.7V minimum input lets this part start up and regulate from a single alkaline cell (nominal 1.5V, end-of-life ~0.9V) or a Li-ion cell deep into discharge. The 5.5V input maximum covers USB power, 2-cell alkaline stacks, and regulated 3.3V or 5V rails without risk. The 200mA switch current limit sets a practical output power ceiling of roughly 1W at 5V — enough for a sensor node, RF transmitter, or small microcontroller rail. ## Up to 2MHz switching — inductor sizing and noise Switching at up to 2MHz lets the designer use small, low-profile inductors (typically 2.2µH to 4.7µH) and ceramic output capacitors, shrinking the total solution footprint. The synchronous rectifier improves efficiency at light loads compared to a diode-based boost, which matters for battery life in always-on applications. The high switching frequency pushes the fundamental switching noise above the AM radio band, simplifying input filter design in sensitive RF systems.","metaTitle":"TI TPS61222MDCKTEP Boost Converter, 0.7V-5.5V Input","metaDescription":"Texas Instruments TPS61222MDCKTEP step-up DC-DC converter. 0.7V to 5.5V input, 5V fixed output, 200mA switch, up to 2MHz switching.","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-Up","Topology":"Boost","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-TSSOP, SC-88, SOT-363","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"200mA (Switch)","Number of Outputs":"1","Base Product Number":"TPS612","Output Configuration":"Positive","Frequency - Switching":"Up to 2MHz","Operating Temperature":"-55°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"0.7V","Voltage - Output (Max)":"-","Supplier Device Package":"SC-70-6","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.1200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b63a48a4af5d1e17ee38e9d6377f1d30.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the switching frequency of TPS61222MDCKTEP?","answer":"The switching frequency is up to 2MHz.
