UC2872Q TI Fluorescent Lamp Driver | 20-PLCC (9x9) | 500V, 100kHz

Product Overview

The UC2872Q from Texas Instruments is a high-voltage resonant-mode fluorescent lamp driver designed for cold cathode fluorescent lamps (CCFL) and other gas discharge lamps. It integrates a half-bridge driver with a 500V rating, making it suitable for backlighting applications in LCD displays, automotive dashboards, and industrial lighting. The device operates at frequencies up to 100kHz and features a built-in oscillator, error amplifier, and protection circuits.
