Typical operating characteristics
OUT1 and OUT2 output efficiency vs load current
Figure 24 and Figure 25 show the efficiency versus load current in PWM mode, skip mode
and no-audible skip mode for different input voltage values:
● GREEN: 7 V
● BLUE: 12 V
● RED: 18 V
Figure 24. Efficiency OUT1 = 5 V T_ON = V_CC
