EMC Considerations: TDK Innoveta power
modules are designed for use in a wide
variety of systems and applications. With
the help of external EMI filters and careful
layout, it is possible to meet CISPR 22 class
A or B requirement. For assistance with
designing for EMC compliance, please
contact TDK Innoveta technical support.
Input Impedance: The source impedance
of the power feeding the DC/DC converter
module will interact with the DC/DC
converter. To minimize the interaction, one
or more 220uF to 470uF/100V input
electrolytic capacitors should be present if
the source inductance is greater than 4uH.
Reliability:
The power modules are designed using TDK
Innoveta’s stringent design guidelines for
component derating, product qualification,
and design reviews. Early failures are
screened out by both burn-in and an
automated final test. The MTBF is
calculated to be 2.9M hours at nominal
input, full load, and Ta = 40˚C using the
Telcordia TR-332 issue 6 method.
Improper handling or cleaning processes
can adversely affect the appearance,
testability, and reliability of the power
modules. Contact TDK Innoveta technical
support for guidance regarding proper
handling, cleaning, and soldering of TDK
Innoveta’s power modules.
Quality:
TDK Innoveta’s product development
process incorporates advanced quality
planning tools such as FMEA and Cpk
analysis to ensure designs are robust and
reliable. All products are assembled at ISO
certified assembly plants.
Safety Considerations:
For safety agency approval of the system in
which the DC-DC power module is installed,
the power module must be installed in
compliance with the creepage and clearance
requirements of the safety agency. The
isolation is basic insulation. For
applications requiring basic insulation, care
must be taken to maintain minimum
creepage and clearance distances when
routing traces near the power module.
As part of the production process, the power
modules are hi-pot tested from primary and
secondary at a test voltage of 1500Vdc.
To preserve maximum flexibility, the power
modules are NOT internally fused. An
external input line normal blow fuse with a
maximum value of 15A is required by safety
agencies. A lower value fuse can be
selected based upon the maximum dc input
current and inrush energy of the module.
When the supply to the DC-DC converter is
less than 60Vdc, the power module meets
all of the requirements for SELV. If the
input voltage is a hazardous voltage that
exceeds 60Vdc, the output can be
considered SELV only if the following
conditions are met:
1) The input source is isolated from the
ac mains by reinforced insulation.
2) The input terminal pins are not
accessible.
3) One pole of the input and one pole of
the output are grounded or both are
kept floating.
4) Single fault testing is performed on the
end system to ensure that under a
single fault, hazardous voltages do not
appear at the module output.
