Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating ratings are conditions under which

the device operates correctly. Operating Ratings do not imply ensured performance limits.

(2)

The SW pin can have -2V to -0.5 volts applied for a maximum duty cycle of 10% with a maximum period of 1 second. There is no duty

cycle or maximum period limitation for a SW pin voltage range of -0.5V to 30 Volts.

(3)

resistance,

TA of 25°C, the maximum allowable power dissipation is 3W.
