It integrates the switching FET internally. The part drives up to four LED strings at 50 mA each, with a maximum output voltage of 40 V. Dimming is via PWM. Input supply range is 2.7 V to 22 V. ## Package and assembly considerations The LP8551TLE/NOPB comes in a 25-bump DSBGA (25-DSBGA) — a fine-pitch wafer-level package. That means the PCB land pattern needs tight registration, and post-reflow X-ray inspection is the norm to confirm solder-joint integrity under each bump. It is surface-mount only; no socket option exists. The operating temperature range is -30°C to 85°C, which suits indoor commercial and industrial equipment but not under-hood automotive or extended outdoor exposure where -40°C is common. ## Lifecycle and sourcing posture This part carries an Active lifecycle status with ROHS3 compliance. The /NOPB suffix indicates lead-free / RoHS-compliant finish, which matches the ROHS3 rating.","metaTitle":"LP8551TLE/NOPB LED Driver, DC-DC Boost Regulator, 40V Output","metaDescription":"LP8551TLE/NOPB is a DC-DC boost regulator for backlight LED driving. 4 outputs at 50 mA each, PWM dimming, 40V max output.
