Each of the four outputs delivers up to 30 mA, making it a fit for small-to-medium LCD panels where the forward voltage of the LED string lands within the boost converter's compliance range. ## Dimming flexibility and package reality Dimming control is available through three interfaces — analog, I²C, and PWM — giving the system architect the option to trade off resolution against bus overhead depending on the host controller's peripheral set. Housed in a 24-DSBGA package measuring 2.59 mm x 1.89 mm, the LM36274YFFR demands a board-level layout that accounts for the fine-pitch BGA footprint and the thermal path through the substrate vias. The part is ROHS3 compliant, which satisfies the material restriction requirements for EU and most global markets without additional exemption documentation.","metaTitle":"LM36274YFFR TI 4-ch boost LED driver, 30mA/ch, 29V","metaDescription":"Texas Instruments LM36274YFFR DC-DC boost regulator, 4 outputs at 30mA each, 29V max.
