The 600 kHz switching frequency allows the use of small, low-profile inductors and ceramic capacitors, shrinking the total solution footprint for space-constrained backlight applications. PWM dimming input enables direct brightness control from a microcontroller PWM output without additional level-shifting or external DAC. ## 38 V output and 700 mA switch — sizing the LED string The 38 V output ceiling supports a series string of white LEDs, making this part suitable for small-to-medium LCD backlights in portable instruments, point-of-sale terminals, and industrial displays. The 700 mA switch current limit is the peak current through the internal FET, not the continuous LED current — the actual LED current depends on the sense resistor and boost ratio.","metaTitle":"TPS61161ADRVT DC-DC Boost Regulator, 38V Output, PWM Dimming","metaDescription":"Texas Instruments TPS61161ADRVT DC-DC step-up regulator for LED backlight. 38V output, 700mA switch, 600kHz, PWM dimming, -40°C to 85°C, 6-WSON.","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":"$1.5700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/54c7bad115f1120cbd1f86630e951d51.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61161ADRVT/alternatives.json"},"ai":{"faq":[{"question":"How to dim LEDs using TPS61161ADRVT PWM?","answer":"The part accepts a PWM signal on the dimming input.
