Note 1: LX has internal clamp diodes to GND and IN. Applications that forward bias these diodes should take care not to exceed
Note 2: Package thermal resistances were obtained based on the MAX15066 Evaluation Kit.
Note 3: Continuous operation at full current beyond +105NC can degrade product life.

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.
