Description
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).
The operating voltage range is wide, so an external
regulator isn’t necessary to supply voltage to the IC.
The FAN7319 provides various protections, such as
open-lamp regulation, open-lamp protection, short-lamp
protection, CMP-high protection, and FB-high protection,
to increase the system reliability. The FAN7319 provides
burst dimming function and analog dimming.
The FAN7319 is available in a 20-Lead Small Outline
Integrated Circuit (SIOC) package.
