succeeding circuitry. Care should be taken in the layout of such
traces to avoid this possibility.
POWER CONSUMPTION
The power converter in the ADuM5230 provides 13 mA of
power to the secondary in its default configuration. Power is
provided to both the data channel, V
chip use. Current consumption of V
shown in Figure 8. The maximum available power for external
use decreases as the frequency of the data channel increases to
stay within the total available current.
INCREASING AND DECREASING AVAILABLE POWER
The V
at the V
given load or the increase of the maximum V
power can also be reduced when it is not required at the output,
lowering the quiescent current and saving power.
Power adjustment is accomplished by adding a voltage divider
between V
normal operation, the V
bias network to set the duty factor of the internal PWM. If the
V
than the default can be chosen. The relationship between the
duty factor of the internal PWM and the available power under
ADJ
pin is connected via a resistor divider, a duty factor other

chosen, the values of the upper and lower divider resistors can
be chosen as shown in Figure 14, which assumes a 10 kΩ total
divider resistance.
COMMON-MODE TRANSIENT IMMUNITY
In general, common-mode transients consist of linear and
sinusoidal components. The linear component of a common-
mode transient is given by
where ΔV/Δt is the slope of the transient shown in Figure 19
and Figure 20.
The transient of the linear component is given by
The ability of the ADuM5230 to operate correctly in the
presence of linear transients is characterized by the data in
Figure 22. The data is based on design simulation and is the
maximum linear transient magnitude that the ADuM5230 can
tolerate without an operational error. This data shows a higher
level of robustness than what is shown in Table 1 because the
transient immunity values obtained in Table 1 use measured
data and apply allowances for measurement error and margin.
