Noise Reduction Measurement
REDUCING RIPPLE NOISE
If ripple noise from the converter is not measured, the results may
differ greatly depending on the measurement method. Therefore,
when measuring ripple noise, be sure to measure the noise from
the root part of the output terminal and not to make a loop so that
magnetic flux is not collected when connecting the probe.
Please keep in mind that spike voltage may vary greatly depending
on the ripple voltmeter and the frequency range of the oscillo-
scope.
TDK measures noise using the following wiring at a frequency
range of 50MHz.
INPUT RIPPLE NOISE
This series contains a capacitor at the input location. Therefore, it
is possible to be operated without connecting an external capacitor
for the input. However, if a capacitor is connected, it is possible to
reduce input ripple noise and input return noise. Input ripple noise
can be reduced even further when a π type filter is used as shown
in the following diagram.
When the distance between the input power source and the input
location of the converter is great, install a capacitor near an input
terminal as much as possible.
When the distance between the input power source and the input
location of the converter is great, the impedance of the input line
becomes high and spike noise may also increase.
Therefore, in such cases, it is recommended to connect the capac-
itor as close to the input location of the DC to DC converter as pos-
sible.

Ripple
OUTPUT RIPPLE NOISE
In order to reduce output ripple noise, connect the capacitor to the
output portion of the converter. Output ripple noise can be
reduced even further when a π type filter is used as shown in the
following diagram. If such a filter is used, please use a coil upto
100µH.
When the distance between the converter output and the load is
great, connect the capacitor to the root portion of the load. To
reduce output spike noise, connect a ceramic capacitor with 0 to
1µF to the output portion of the converter.
OUTPUT EXTERNAL CAPACITANCE RANGES
Please keep in mind that if the capacitor installed at the output
location has a larger capacity than shown in the following value, or
if capacitors with low impedance are connected parallel much,
converter operation may be unstable.
