PWM dimming input allows brightness control directly from a microcontroller or backlight controller without an external DAC. The 1.1 A switch current limit is the peak current the internal NMOS can handle before the cycle-by-cycle current limit engages. For a boost converter driving an LED string, this sets the maximum output current at a given input-to-output voltage ratio. At a typical 3.6 V input and 17 V output, the available LED current is roughly 200 mA — enough for a medium-brightness backlight in a 7-inch panel. Below 2.5 V the part will not start; above 6 V the absolute maximum is exceeded, so a pre-regulator or separate rail is needed if the system bus is 12 V. The TPS61166DSKT comes in a 10-WFDFN exposed pad package (10-SON, 2.5x2.5 mm body). Surface-mount assembly per the standard reflow profile for MSL1/2 devices applies. The small 2.5 mm x 2.5 mm footprint suits space-constrained portable equipment such as handheld terminals, medical monitors, and portable instrumentation.","metaTitle":"TI TPS61166DSKT boost converter, 17 V, 1.1 A switch","metaDescription":"Texas Instruments TPS61166DSKT is a 1.2 MHz step-up DC-DC regulator with integrated switch, 17 V output, 1.1 A switch current limit, PWM dimming, industrial","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Regulator","Series":"-","Dimming":"PWM","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"1.2MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"17V","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"TPS61166","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"6V","Voltage - Supply (Min)":"2.5V","Supplier Device Package":"10-SON (2.5x2.5)","Current - Output / Channel":"1.1A (Switch)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6f736e6732b56945f12e313316388620.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61166DSKT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61166DSKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61166DSKT when reusing this data.
