FAN7318A Datasheet, PDF (7/24 Pages) Fairchild Semiconductor – LCD Backlight Inverter Drive IC

Electrical Characteristics (Continued)
For typical values, TA=25°C, VIN=15V, and -25°C ≤ TA ≤ 85°C, unless otherwise specified. Specifications to -25°C ~
85°C are guaranteed by design based on final characterization results.
