The frequency is high enough to push switching noise above the AM band, simplifying input filter design for automotive and industrial environments. ## Output voltage range and current capability With an output adjustable from 3 V to 38 V, the part can drive a single high-voltage LED or a string of up to ten white LEDs in series, depending on forward voltage. The internal switch is rated for 1.2 A peak, which at 38 V output translates to roughly 30 W of output power — enough for a medium-sized automotive display backlight or a 7-inch industrial panel.","metaTitle":"TPS61165DBVT DC-DC Boost Regulator, 1.2 MHz, SOT-23-6","metaDescription":"Texas Instruments TPS61165DBVT is a DC-DC boost regulator with PWM dimming, 1.2 MHz switching, 3-38 V output, 1.2 A switch, SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"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":"Automotive, Backlight","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"3V ~ 38V","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"TPS61165","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"18V","Voltage - Supply (Min)":"3V","Supplier Device Package":"SOT-23-6","Current - Output / Channel":"1.2A (Switch)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/00c483322e29e2f34fee07470a81b600.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61165DBVT/alternatives.json"},"ai":{"faq":[{"question":"Can TPS61165DBVT be used with a 12 V input?","answer":"Yes. The supply voltage range is 3 V to 18 V, so a 12 V automotive or industrial rail is well within the operating envelope. The output can be set to any voltage between 3 V and 38 V to match the LED string forward voltage."},{"question":"What is the equivalent or alternative to TPS61165DBVT?","answer":"No official pin-compatible equivalent is listed in the TI portfolio for this SOT-23-6 package variant. The base product number TPS61165 covers several package options; the DBVT suffix identifies the SOT-23-6 tape-and-reel version.
