LCD Backlight Inverter Drive IC

Fairchild Semiconductor 

Electrical Characteristics (Continued)

For typical values TA=25°C and VIN=18V. For min./max. values, TA is the operating ambient temperature range with

-25°C ≤ TA ≤ 85°C and 4.5V ≤ VIN ≤ 18V, unless otherwise specified. Specifications to -25°C ~ 85°C are guaranteed by

design based on final characterization results.
