NAME

CGND

I/O

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.

PGND

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.
