Absolute Maximum Ratings
CAUTION: Absolute Maximum ratings are stress ratings only. Functional operation beyond the recommended operating
conditions is not implied. Stress beyond the absolute maximum ratings may impair device life. Exposure to absolute
maximum rated conditions for extended periods may affect device reliability.

Note 1: PVIN rising and falling slew rates cannot be outside of specification. For accurate power up sequencing, use a
fast ENABLE logic after both AVIN and PVIN is high.
Note 2: Maximum V_OUT ≤ V_IN - 2.5V
Note 3: Based on 2oz. external copper layers and proper thermal design in line with EIJ/JEDEC JESD51-7 standard for
high thermal conductivity boards.
