Six independent current sinks allow per-string current matching, critical for uniform panel brightness across the full dimming range. The 450 mA per-channel rating supports parallel LED configurations where each string draws up to that current; total output power is limited by the boost converter's input power budget and thermal dissipation in the 25-DSBGA package. ## Package and board integration — 25-DSBGA The 25-bump DSBGA is a wafer-level chip-scale package with a 0.4 mm pitch typical for this bump count. The small footprint — roughly 2.2 mm × 2.2 mm — saves board area but demands a controlled reflow profile and X-ray inspection after assembly to confirm solder-joint integrity under each bump. ## Compliance and documentation Texas Instruments lists the LP8552TLE-E04/NOPB as ROHS3 compliant, meeting the EU RoHS exemption framework without conflict.","metaTitle":"LP8552TLE-E04/NOPB TI Boost LED Driver, 6-Ch 450mA PWM","metaDescription":"Texas Instruments LP8552TLE-E04/NOPB DC-DC boost regulator, 6 outputs at 450 mA each, 40 V max, PWM dimming, 25-DSBGA.
