Achieving fast slew rates under specific line and load conditions may require feedback loop adjustment
If the voltage sense outputs are connected remotely, it is recommended to place a 0.01-0.1 μ F ceramic capacitor between +VS and –VS pins
as close to the POL converter as possible. The capacitor improves noise immunity of the POL converter.
