FUNCTION
Connect to GND plane at all times.
Not a perimeter pin. Device thermal pad to be connected to the system GND
plane for heat-sinking purposes.
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: RCLX resistor value may need to be raised for V_OUT > V_IN – 2.5V to increase current limit threshold.
Note 2: Based on 2oz. external copper layers and proper thermal design in line with EIJ/JEDEC JESD51-7 standard for
high thermal conductivity boards.
