ELECTRICAL CHARACTERISTICS
Note 4: Dynamic supply current is higher due to the internal gate charge
being delivered at the switching frequency.
Note 5: TJ is calculated from the ambient temperature TA and power
dissipation PD as follows:
LTC3416E: TJ = TA + (PD)(38°C/W)
LTC3416
Note 6: This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125°C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
