IDD is calculated using IDD = (ICC× VCC)/(VDD×η), where ICC is the class D amplifier quiescent current; η = 40%, which is the boost
converter efficiency when class D amplifier has no load. To achieve the minimal 40%
η, it is recommended to use the suggested
inductors in table 4 and to follow the layout guidelines.
