Note 1: The maximum allowable power dissipation is a function of maximum operating junction temperature, TJ (max), the junction to ambient thermal resistance, and
the ambient,
θJA, and the ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is given:
PD (max) = (TJ(max) - TA)
θJA. Exceeding the maximum allowable power limit will result in excessive die temperature; thus, the regulator will go into thermal shutdown.
The
θJA of the AS8863 is 220oC/W mounted on a PC board.
Note 2: Not apply to 1.8V version.
