What this part is
The NXP UBA20262T/1518 is a high-voltage integrated circuit designed as a driver for compact fluorescent lamps (CFL), packaged in a 20-SOIC. It belongs to the Discrete Semiconductors category, reflecting its role as a power management and lamp ballast component.
The 20-SOIC body width and lead pitch are industry-standard, so the PCB layout footprint is well-documented and does not require custom pad geometry.
