6.1 Absolute Maximum Ratings(1)

MIN MAX UNIT
Voltage at pins(2) PVIN, AVIN, FB, SS, EN, DEF, VOS – 0.3 7 V
SW (DC), PG – 0.3 VIN+0.3
SW (AC, less than 10 ns)(3) – 3.0 10
CN, CP – 0.3 VIN+7.0
Sink current PG 1.0 mA
Operating junction temperature range, TJ – 40 150 °C
Storage temperature, Tstg – 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 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 pin.
(3) While switching.

6.2 ESD Ratings

MAX UNIT
