A4401
Automotive Quasi-Resonant Flyback Control IC
The capacitance selection has been dealt with in the
Input Capacitor Selection section. In terms of select-
ing an inductance, generally the higher the inductance
the better as far as noise rejection of the differen-
tial conducted emissions is concerned. However, a
large inductance usually means additional cost and
increased size, therefore, it is advisable to select an
inductance as large as possible within the constraints
of board space and cost.
The maximum average current that flows through the
inductor is similar to the maximum average current
that was worked out in the Current Sense Resistor
Selection section. Both the rms and saturation current
ratings of the inductor selected should be higher than
the maximum average current. Care should be taken
when selecting inductors for operation at elevated tem-
peratures, because some manufacturers rate their parts
using only self-generated heating, giving the impres-
sion of operability at higher temperature conditions.
