1) The maximum obtainable average current value is dependent on the chosen PWM frequency, the chosen dither amplitude,
and the load impedance.
2) This value corresponds to the maximum evaluated life time drift according to AEC-Q100 grade 1.
3) The minimum and maximum achievable PWM frequencies depend on the load characteristics.
