(1) Operating at high VIN can create excessive AC voltage overshoots on the switch node (VSW) during MOSFET switching transients. For reliable operation, the switch node (VSW) to ground voltage must remain at or below the Absolute Maximum Ratings.
(2) Measurement made with six 10-µF (TDK C3216X7R1C106KT or equivalent) ceramic capacitors across VIN to PGND pins.
(3) System conditions as defined in Note 2. Peak output current is applied for tp = 50 µs.
