6.1 Absolute Maximum Ratings

Over the recommended operating junction temperature range of –40°C to +125°C (unless otherwise noted)(1)
MIN MAX UNIT
Input voltages VIN –0.3 26 V
EN –0.3 6
BOOT –0.3 SW+6
FB –0.3 6
Output voltages BOOT-SW –0.3 6 V
SW –0.3 26
SW (<10 ns transient) –3 26
TJ Operating junction temperature(2) –40 150 °C
Tstg Storage temperature –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) Operating at junction temperatures greater than 125°C, although possible, degrades the lifetime of the device.
