Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Pin voltage range(1) VIN -0.3 6.5 V
SW -0.3 VIN+0.3 V
SW (transient for less than 10 ns)(2) -3 10 V
FB -0.3 4 V
PG, FB, SS/TR, COMP/FSET -0.3 VIN+0.3 V
EN, MODE/SYNC -0.3 6.5 V
Storage temperature, Tstg -65 150 °C
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.
