It integrates a 1.2 A switch and operates at a fixed 1.2 MHz switching frequency, which keeps the external inductor small and the ripple within the EMI budget for automotive backlight applications. The output can be set from 3 V up to 38 V via external resistor divider, which covers a string of up to ten white LEDs in series (typical forward voltage ~3.2 V each). PWM dimming is supported directly on the control pin, giving the designer a linear brightness range without colour shift — the dimming frequency and duty cycle are set by the host controller, not the regulator. ## Temperature grade and automotive suitability It is not qualified to AEC-Q100, so for under-hood or mission-critical automotive ECUs a fully AEC-qualified boost driver should be selected. The SOT-23-6 package is surface-mount and reflow-compatible with standard lead-free profiles. ## Supply range and input headroom Input supply range is 3 V minimum to 18 V maximum, covering single-cell Li-Ion, 5 V USB, or 12 V automotive rails. The 3 V minimum allows operation from a nearly depleted Li-Ion cell, which is useful for portable backlight or battery-backed display modules.","metaTitle":"TPS61165DBVR Boost LED Driver, 1.2 MHz, 38V Output, SOT-23-6","metaDescription":"Texas Instruments TPS61165DBVR DC DC regulator, step-up boost topology, 1.2 MHz switching, 3V to 38V output, 1.2A switch, PWM dimming, SOT-23-6, -40°C to 85°C.","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":"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":"$2.1600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/00c483322e29e2f34fee07470a81b600.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61165DBVR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS61165DBVR support PWM dimming?","answer":"Yes, PWM dimming is supported.
