7.  The current value corresponds to the PoEPD input current (the current flowing in the external Rdet and the quiescent current of the device
are included). Resistors are assumed to have 1% accuracy.
8.  Power dissipation must be considered. Load on VDDH and VDDL must be limited especially if VDDH is not powered by an auxiliary winding.
9.  Ivddl_load = current flowing out of the VDDL pin.
Ivddh_load = current flowing out of the VDDH pin + current delivered to the Gate Driver (function of the frequency, VDDH voltage & MOSFET
gate capacitance).
