It integrates a 200mA switch and synchronous rectifier, so you get decent efficiency without an external Schottky diode. Typical use cases are single-cell alkaline, NiMH, or Li-ion battery-powered gear where you need a 1.8V to 5V rail for an MCU, sensor, or RF link. ## Switching frequency and output current — sizing the rail Switching frequency goes up to 2MHz, which lets you use small inductors and ceramics — handy when board space is tight. The 200mA switch current is the peak limit through the internal FET; actual output current depends on the input-to-output voltage ratio. From a 1.2V input making 3.3V, expect around 60–70 mA continuous output before the switch current limit kicks in. That is enough for a small MCU plus a few peripherals, but not for a motor or radio transmitter. The SC-70-6 package is small — about 2.1 mm × 2.0 mm — which means you can fit it on a cramped board, but the thermal dissipation is limited. For loads near the 200mA switch limit, keep the copper pour on the PCB generous.","metaTitle":"TPS61220DCKR Step-Up Boost Converter, 200mA Switch, SC-70-6","metaDescription":"Texas Instruments TPS61220DCKR step-up boost converter with 0.7V min input, 200mA switch, adjustable output to 6V.","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-Up","Topology":"Boost","Output Type":"Adjustable","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":"TPS61220","Output Configuration":"Positive","Frequency - Switching":"Up to 2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"0.7V","Voltage - Output (Max)":"6V","Supplier Device Package":"SC-70-6","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c57d0f02ab0ce74374402c9069b0cff5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to TPS61220DCKR?","answer":"The TPS61220DSE is the same base part in a different package (DSBGA-8).
