FAN7319

Overview

The FAN7319 is a LCD backlight inverter drive IC that controls N-N push-pull topology or N-N full-bridge topology using a proprietary phase-shift method. The FAN7319 provides a low-cost solution and reduces external components by integrating full-wave rectifiers for open-lamp protection and regulation (patent pending).
