6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
VIN, EN Unregulated input(2)(3) –0.3 45 V
VOUT Regulated output –0.3 7 V
SI Sense input(2) –0.3 VIN V
CT Reset delay input –0.3 25 V
FB, SO, PG Feedback, sense output, power good –0.3 VOUT V
TJ Operating junction temperature range –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, 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 GND
(3) Absolute maximum voltage, withstand 45 V for 200 ms
