UBA2021T/N2,512

Lighting, Ballast Controllers Overview

The UBA2021T/N2,512 is a high-voltage integrated circuit designed for driving and controlling Compact Fluorescent Lamps (CFL) or fluorescent TL lamps. It integrates a driver circuit for an external half-bridge, an oscillator, and control logic for startup, preheating, ignition, lamp operation, and protection. The device operates within a frequency range of 41.21kHz to 44.59kHz and requires a supply voltage between 10.15V and 11.95V. It features a 14-SOIC package with a width of 3.90mm and supports surface mount installation. The component functions reliably across a temperature range of -40°C to 150°C.
