temperature (TJ in °C) is calculated from ambient temperature (TA in °C)

and power dissipation (PD in Watts) according to the formula: TJ = TA +

(PD • θJA), where θJA (in °C/W) is the package thermal impedance.

The LTC3306 includes overtemperature protection that protects the device

during momentary overload conditions. Junction temperatures will exceed

150°C when overtemperature protection is engaged. Continuous operation

above the specified maximum operating junction temperature may impair

device reliability.

Note 3: Supply current specification does not include switching currents.

Actual supply currents will be higher.
