Absolute Maximum Ratings

over operating temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Pin voltage(2) VIN – 0.3 6.5 V
Pin voltage(2) SW (DC) – 0.3 VIN + 0.3 V
Pin voltage(2) SW (AC, less than 10ns)(3) – 3 10 V
Pin voltage(2) COMP/FSET, PG – 0.3 VIN + 0.3 V
Pin voltage(2) EN, MODE/SYNC, FB – 0.3 6.5 V
Tstg Storage temperature –65 150 °C
Stresses beyond those listed under Absolute Maximum Rating 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 Condition. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to the network ground terminal
