Electrical characteristics
Unless otherwise specified, all ratings below are for -40°C < T_J < 125°C, V_SP = 42V, V_SM =
0V and the application circuit of Figure 12. Operation of the IC above this junction
temperature will continue without audible artifacts until thermal shutdown, but these
parameters are not guaranteed to be within the specifications below. F_PWM=110KHz,
Booster not enabled.
