6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range unless otherwise noted(1)
MIN MAX UNIT
Input voltage at VIN(2) –0.3 6 V
Input voltage at IN(2) VIN V
Minimum voltage at OUT (2) –18 V
Voltage at EN, FB, COMP, PS_GND (2) –0.3 VIN + 0.3 V
Differential voltage between OUT to VIN (2) 24 V
Operating virtual junction temperature, TJ –40 150 °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.
(2) All voltage values are with respect to network ground terminal, unless otherwise noted.

6.2 ESD Ratings
