6.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)| MIN | MAX | UNIT | |
|---|---|---|---|
| Input voltage range on SW, VOUT, VBAT, EN, FB | –0.3 | 7 | V |
| Operating virtual junction temperature, TJ | –40 | 150 | °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, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
