At this frequency, the fundamental switching harmonic falls below the AM broadcast band, which helps pass radiated emissions in consumer display products. ## 38 V output and LED string count With a 38 V maximum output, the TPS61161DRVR can drive up to ten white LEDs in series (assuming ~3.2 V forward voltage per LED at nominal current). The actual count depends on the forward voltage drop at the programmed current and the headroom required for the current-sense resistor. The 700 mA switch current limits the total power to about 26 W at 38 V, but in practice the thermal dissipation in the 6-WSON package constrains continuous output to lower levels — derating is necessary above 70°C ambient. ## Package and thermal: 6-WSON exposed pad Without adequate thermal management, the switch current derates above 70°C ambient.","metaTitle":"TPS61161DRVR DC DC Regulator, Boost, 38V Output, 600kHz","metaDescription":"Texas Instruments TPS61161DRVR DC DC regulator, step-up boost topology, 38V output, 700mA switch, PWM dimming, 6-WSON package, active lifecycle.","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":"600kHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"38V","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"TPS61161","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"18V","Voltage - Supply (Min)":"2.7V","Supplier Device Package":"6-WSON (2x2)","Current - Output / Channel":"700mA (Switch)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d7616a7f890b06523c0db11fd02e1202.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61161DRVR/alternatives.json"},"ai":{"faq":[{"question":"How many LEDs can TPS61161DRVR drive?","answer":"With a 38 V output ceiling, the TPS61161DRVR can drive up to ten white LEDs in series at typical forward voltage (3.2 V each).
