Two independent outputs each deliver up to 27V at 34mA, with integrated switches that eliminate the need for external MOSFETs. PWM dimming is supported directly on the control pin, allowing the host processor to set brightness by varying the duty cycle of the dimming signal. The 1.2 MHz switching frequency keeps the inductor and output capacitors small — a 4.7 µH to 10 µH inductor and 1 µF ceramic output cap are typical for a 3-LED series string. Input supply range spans 2.5V to 6V, so the part runs from a single Li-ion cell (3.0V–4.2V) or a regulated 3.3V/5V rail without a separate bias supply. ## Output voltage and current — matching the LED string Each of the two channels is rated for 34mA continuous output current at 27V maximum. That 27V ceiling accommodates up to six white LEDs in series (assuming ~3.2V forward drop per LED) with headroom for the current-sense resistor. If the application needs more than 34mA per channel, this part is not the right fit — the output current is fixed by the internal current-sense threshold. The boost topology means the input current at 2.5V minimum supply can reach about 400 mA at full load (two channels, 34mA each, 27V output, 85% efficiency estimate).","metaTitle":"TPS61150ADRCT DC-DC Boost Regulator, 27V Output, PWM Dimming","metaDescription":"Texas Instruments TPS61150ADRCT dual-output boost regulator for LED backlight. 27V output, 34mA per channel, PWM dimming, 1.2MHz switching, -40°C to 85°C.","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":"Backlight","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"27V","Number of Outputs":"2","Internal Switch(s)":"Yes","Base Product Number":"TPS61150","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"6V","Voltage - Supply (Min)":"2.5V","Supplier Device Package":"10-VSON (3x3)","Current - Output / Channel":"34mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1caf213087ffafcbe1cbc2e727db27d8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61150ADRCT/alternatives.json"},"ai":{"faq":[{"question":"Does TPS61150ADRCT support PWM dimming?","answer":"Yes, the TPS61150ADRCT supports PWM dimming.
