Input current Continuos average current into L1(3) 2.7 A
Operating junction temperature, TJ –40 125 °C
Storage temperature, Tstg –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground pin.
(3) Maximum continuos average input current 3.5 A, under those condition do not exceed 105°C for more than 25% operating time.

8.2 ESD Ratings
