(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating

Conditions are not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

A maximum of 42 V can be sustained at this pin for a duration of

≤ 500 ms at a duty cycle of ≤ 0.01%.

(3)

A voltage of 2 V below PGND and 2 V above VIN can appear on this pin for

≤ 200 ns with a duty cycle of ≤ 0.01%.

(4)

Do not exceed the voltage rating on this pin.

An extended input voltage range to 3.5 V is possible; see System Characteristics table. See Input UVLO for start-up conditions.

(2)

The output voltage must not be allowed to fall below zero volts during normal operation.

(3)

Operation below 3.3 V and above 6 V may require changes to the typical application schematic, operation may not be possible over the

full input voltage range, and some system specifications will not be achieved for this extended output voltage range. Consult the factory

for further information.

(4)

High junction temperatures degrade operating lifetime.

7.3 Recommended Operating Conditions

Over the recommended operating junction temperature range of –40°C to +150°C (unless otherwise noted).
