Notes: 1. Pt(25) represents a PCB temperature of 25°C, and Pt(110) represents 110°C.

2. Rated voltages are relative to voltages on the SGND and PGND pins.

3. For rated current, (+) indicates inflow to the chip and (–) indicates outflow.

4. Ratings for which “ac” is indicated are limited to within 100 ns.
