Take the power consumption and power dissipation into consideration. 2. When implemented on a standard board (70 x 70 x 1.6 mm, Cu 3%, Single-sided glass epoxy board). The value reduces at a rate of about 4.7 mW/C when the IC is used at Ta = 25C or higher. Electrical Characteristics (Ta = 25C, V = 12V) CC Spec. Applicable Item Symbol Condition Unit terminal Min.
