The 2.8 A internal switch rating sets the output current ceiling — at 24 V output from a 5 V rail, the available LED current is duty-cycle limited, but the switch handles the peak without an external FET. PWM dimming is handled through the control loop, not a series pass element, so the dimming ratio is set by the PWM frequency and the 525 kHz switching frequency — the inductor ripple current stays within the core loss budget across the dimming range. ## Supply rails and output compliance Input supply range runs from 2.7 V minimum to 5.5 V maximum — this covers a single lithium-ion cell (3.0-4.2 V) or a regulated 3.3 V / 5.0 V rail. The output voltage adjusts from 3 V up to 24 V, which suits backlight strings with 6 to 8 white LEDs in series, each dropping roughly 3 V. Single output channel with the internal switch rated at 2.8 A — the actual LED current is set by the external sense resistor and the feedback voltage. The 525 kHz fixed frequency keeps the inductor physically small; a 10 µH shielded inductor in the 4x4 mm footprint is typical for a 350 mA string. ## Package and board integration Without this, the junction-to-ambient thermal resistance rises above the 40 °C/W typical figure, and the 125 °C junction limit is reached at lower output current. The wide range suits outdoor backlight modules or industrial displays that see enclosure temperatures above 85 °C.","metaTitle":"Texas Instruments LM3410YMY/NOPB LED Driver, 2.8A Switch","metaDescription":"Active production LM3410YMY/NOPB DC-DC regulator LED driver.
