It integrates six current-sink outputs, each rated for 30 mA, and delivers a regulated output voltage up to 38 V — enough to drive multiple LED strings in series from a single lithium-ion or 5 V rail. Dimming is handled via PWM input, giving the display controller direct control over LED brightness without analogue drift. Input supply range spans 4.5 V to 24 V, covering common rails from a single-cell Li-ion (3.7 V boosted to 5 V) up to a 24 V industrial bus. Housed in a 20-pin WFQFN with exposed pad (4x4 mm body), the TPS61187RTJR requires a surface-mount reflow process.","metaTitle":"TPS61187RTJR Boost LED Driver, 6-Ch, 38 V, 1 MHz, Active","metaDescription":"Texas Instruments TPS61187RTJR DC DC boost regulator for backlight. 6 outputs at 30 mA each, 38 V max, 1 MHz switching, PWM dimming.","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":"1MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"20-WFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"38V","Number of Outputs":"6","Internal Switch(s)":"Yes","Base Product Number":"TPS61187","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"24V","Voltage - Supply (Min)":"4.5V","Supplier Device Package":"20-QFN (4x4)","Current - Output / Channel":"30mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9870","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/69489d743bcb458796cabce39866f86c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61187RTJR/alternatives.json"},"ai":{"faq":[{"question":"What is the switching frequency of TPS61187RTJR?","answer":"The switching frequency is 1 MHz.
