Dimming is handled digitally via I²C or SPI bus, so the host processor can set individual channel brightness without external PWM generators. The 2 MHz switching frequency keeps the external inductor small enough for a compact backlight board. Supplied in a 36-bump WFBGA or DSBGA package (0.5 mm pitch typical for this class), the LP55281TLX/NOPB requires a surface-mount reflow profile suited to lead-free solder. The internal switch is integrated (no external FET needed), so the BOM stays lean: one boost inductor, input/output caps, and the LED current-set resistors per channel. ROHS3 compliant per. ## Sourcing and lifecycle posture Sourced through authorized and independent distribution channels. No pin-compatible second source is documented from other manufacturers.","metaTitle":"Texas Instruments LP55281TLX/NOPB LED Driver, 12-Ch, 40mA","metaDescription":"Active Texas Instruments LP55281TLX/NOPB DC-DC boost LED driver, 12 outputs at 40 mA each, I²C/SPI dimming, 36-DSBGA.
