The 40V output ceiling means it can power series strings of LEDs — common in backlight panels where each string needs a consistent current. The 450 mA switch current limit sets the total power budget: at 40 V output, that is about 18 W before derating. ## PWM dimming and supply range Dimming is controlled via a PWM input — the internal logic modulates the switch duty cycle to adjust LED brightness without audible noise. The supply range spans 2.7 V to 22 V, covering single-cell Li-ion up to a 12 V rail. Operating temperature is -30°C to 85°C, which covers most indoor and automotive cabin applications but not under-hood extremes. The 25-DSBGA package (2.46 x 2.46 mm) is a fine-pitch BGA — a 4-layer PCB with micro-vias is recommended for fan-out. Texas Instruments provides RoHS and REACH compliance documentation for this part.","metaTitle":"LP8550TLX-A/NOPB TI Boost LED Driver, 6 Outputs, 40V","metaDescription":"Active production — Texas Instruments LP8550TLX-A/NOPB DC-DC boost regulator, 6 outputs, 40V, PWM dimming, 25-DSBGA.

The TLC69611RTWR is also a linear constant-current driver. Neither is a drop-in replacement for the LP8550TLX-A/NOPB; the topology (boost vs linear) and pinout differ.
