di/dt = 0.1 A/µs, Vin = 48 Vdc, Tc = 25 °C, load change = 0.5 lo max. to
0.75 lo max. and 0.75 lo max. to 0.5 lo max. Deviation varies by model, see
Longform Datasheet.
The EXQ125 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
