DYNAMIC ELECTRICAL CHARACTERISTICS
Table 4. Dynamic Electrical Characteristics
Characteristics noted under conditions V IN = 24 V, V PVCC = 12 V, V DVDD = 3.3 V, I LED = 70 mA (Local Dimming Mode);
140 mA (Scan Mode), f S = 700 kHz, f PWM = 660 Hz, GND = 0 V unless otherwise noted. Typical values noted reflect the
approximate parameter means at T A = 25°C under nominal conditions unless otherwise noted.
