[1] Output power is measured indirectly; based on RDSon measurement.
[2] 2 layer application board (55 mm à 45 mm), 35 µm copper, FR4 base material in free air with natural convection.
[3] THD+N is measured in a bandwidth of 20 Hz to 20 kHz, AES17 brick wall.
[4] B = 22 Hz to 20 kHz, AES17 brick wall.
[5] RS is the series resistance of inductor and capacitor of low-pass LC ï¬lter in the application.
