CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product

reliability and result in failures not covered by warranty.

NOTES:

6. Absolute maximum voltage rating is defined as the voltage applied for a lifetime average duty cycle above 6V of 1%.

7.

Brief TB379.

8. For

9. Extended operation at these conditions may compromise reliability. Exceeding these limits will result in damage. Recommended operating conditions

define limits where specifications are guaranteed.

10. Electromigration specification defined as lifetime average junction temperature of +110°C where max rated DC current = lifetime average current.

Applications must follow thermal guidelines of the package to determine worst case junction temperature. Please refer to “ISL78310 Schematic
