3416f

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)

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.
