Switching at a fixed 1.2 MHz, it uses a small inductor and ceramic capacitors to keep the solution footprint compact — a common choice for space-constrained portable or battery-backed rails. ## Input voltage range and output headroom The input range spans 1.6 V to 6 V, so a single Li-Ion cell (3.0 V to 4.2 V), two or three alkaline cells, or a regulated 3.3 V / 5 V rail all fit within the operating envelope. With the output adjustable from 1.6 V up to 17 V, this converter can generate 12 V bias rails, 5 V from a lower battery voltage, or drive a string of white LEDs — the 17 V ceiling gives enough headroom for a 3- or 4-series LED chain. ## Switching frequency and external component sizing The 1.2 MHz switching frequency places the fundamental ripple in the low-MHz band, allowing the use of small-value inductors (typically 4.7 µH to 10 µH) and ceramic output capacitors that keep the total BOM area small. Because the part does not use synchronous rectification (external Schottky diode required), the rectifier forward drop adds to the conduction loss — a 0.4 V to 0.5 V Schottky works well at this voltage and current level. The small footprint (2.5 mm x 2.5 mm) suits portable and space-limited designs, but the pad clearance and via placement under the package need care during layout. ## Active lifecycle — no last-time-buy risk It can be specified for new production builds without a last-time-buy clock, and the base product number TPS61093 remains in the TI portfolio. For dual-sourcing or supply-resilience planning, there is no official second-source pin-compatible alternate from another manufacturer listed on this record.","metaTitle":"Texas Instruments TPS61093DSKR Step-Up Boost Converter","metaDescription":"Active TPS61093DSKR boost regulator from TI: 1.6 V to 6 V input, adjustable output to 17 V, 900 mA switch, 1.2 MHz switching, -40°C to 85°C, 10-WFDFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"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":"10-WFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"900mA (Switch)","Number of Outputs":"1","Base Product Number":"TPS61093","Output Configuration":"Positive","Frequency - Switching":"1.2MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"1.6V","Voltage - Output (Max)":"17V","Supplier Device Package":"10-SON (2.5x2.5)","Voltage - Output (Min/Fixed)":"1.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ac7a80d57a74c6e81b4631680158af05.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61093DSKR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61093DSKR obsolete or active?","answer":"It can be specified for new production without a last-time-buy risk."},{"question":"What is the output current capability of TPS61093DSKR?","answer":"The internal switch is rated for 900 mA peak current.
