Each of the six outputs sinks a regulated 25 mA, and the boost converter delivers up to 38 V on the output rail — enough headroom to stack eight to ten white LEDs in series per channel, depending on their forward voltage at full current. Switching at 1 MHz, the part works with a small inductor and ceramic input/output capacitors, keeping the total power-stage footprint compact. PWM dimming is handled directly on the enable pin, so the host processor can vary brightness without an external PWM generator. ## Output voltage and channel current — sizing the LED load The 38 V output ceiling sets the maximum series LED count per channel. With a typical white LED forward voltage of 3.0–3.4 V at 25 mA, eight LEDs in series require roughly 27 V of compliance, leaving margin for the current-sink headroom and line regulation. Six channels at 25 mA each give a total backlight power budget around 5.7 W at 38 V — the designer should derate for ambient temperature and inductor saturation current. The boost topology means the input voltage range of 5 V to 24 V covers common rails from USB power to automotive battery-derived supplies. At minimum input, the duty cycle climbs, so the inductor ripple current and output ripple deserve a close look during the layout review.","metaTitle":"TPS61180RTERG4 LED Driver, Boost, 6-Ch 25mA, 38V, 1MHz","metaDescription":"Texas Instruments TPS61180RTERG4 DC-DC boost regulator with PWM dimming, 6 outputs at 25 mA each, 38 V max output, 1 MHz switching, active production.","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)","Topology":"Step-Up (Boost)","Frequency":"1MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"16-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Output":"38V","Number of Outputs":"6","Internal Switch(s)":"Yes","Base Product Number":"TPS61180","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"24V","Voltage - Supply (Min)":"5V","Supplier Device Package":"16-WQFN (3x3)","Current - Output / Channel":"25mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1600ce089700f5350292e6d31f66dc34.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61180RTERG4/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for TPS61180RTERG4?","answer":"Submit an RFQ with your target quantity and lead-time window for a current quote."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61180RTERG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61180RTERG4 when reusing this data.
