R
sL
is the series resistance of inductor of low-pass LC filter in the application.

Output power is measured indirectly; based on R
DSon
measurement. See also

Total harmonic distortion is measured in a bandwidth of 22 Hz to 20 kHz, using AES17 20 kHz brickwall filter. Maximum limit is
guaranteed but may not be 100 % tested.
