7.1 Absolute Maximum Ratings

over operating junction temperature range (unless otherwise noted)(1)
MINMAXUNIT
Input voltage(2)VIN–0.37V
Voltage(2)EN, MODE/DATA, DEF_1–0.3VIN + 0.3, ≤ 7V
SW1, SW2–0.37V
ADJ2, FB1–0.3VIN + 0.3, ≤ 7V
CurrentMODE/DATA≤ 0.5mA
Maximum operating junction temperature, TJmax150°C
Storage temperature, Tstg–65150°C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and 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 the network ground terminal.
