di/dt = 0.1A/µs, Vin = 48VDC, Tc = 25°C, load change = 0.5 lo max. to
0.75 lo max. and 0.75 lo max. to 0.5 lo max.
The EXQ50 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
See Application Note 120 for details.
Recommended input fusing is a 3.15A HRC 200V rated fuse.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.

This parameter is calculated at worst case line, load, temperature and
initial settings.
This is inclusive of the output trim range. If 6.0% trim-up is used, for
example, then only 4.0% output sense is available.
