The single-output regulator delivers a regulated output voltage up to 28 V from an input supply ranging from 1.8 V to 6 V. ## 1 MHz switching and 28 V output ceiling The 1 MHz switching frequency places the fundamental ripple and its harmonics well above the audio band, which is a practical advantage in backlight applications where audible noise from ceramic capacitors is a concern. The 28 V output ceiling supports driving a string of six to eight white LEDs in series, depending on their forward voltage at the target current. PWM dimming on the enable pin lets the controller pulse the LED string at a duty cycle set by an external signal, while the output stays regulated. The part carries a standard industrial temperature grade, not AEC-Q100 qualification. ## Active production, SOT-23-5 package The small body size (approximately 2.9 mm x 1.6 mm) suits space-constrained portable designs.","metaTitle":"TPS61041DBVRG4 Boost LED Driver, 28V, 1MHz, SOT-23-5","metaDescription":"Texas Instruments TPS61041DBVRG4 DC-DC boost regulator for LED backlight. 28V output, 1MHz switching, 215mA switch current.

The TPS61041 base product number shares the same pinout and function across its package variants, but no alternate MPN is cited as a drop-in second source. For dual-sourcing inquiries, the RFQ process can verify compatibility against the BOM."},{"question":"How do I design a boost circuit with TPS61041DBVRG4 for LED backlight?","answer":"The part is a current-mode boost regulator with an integrated switch. The application circuit requires an input capacitor, an inductor (typically 4.7 µH to 10 µH for 1 MHz operation), a Schottky rectifier diode, an output capacitor, and a resistor divider to set the output voltage up to 28 V. PWM dimming is applied to the EN pin. The 215 mA switch current limit sets the maximum LED current, which must be calculated from the output voltage and the boost conversion ratio."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61041DBVRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61041DBVRG4 when reusing this data.
