Note 1: LX pin has internal clamps to GND and OUT. These diodes may be forward biased during switching transitions. During

these transitions, the max LX current should be within the maximum RMS current rating for safe operation.

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 in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect

device reliability.
