Design Considerations (continued)
Output Filtering
The Austin MicroLynx TM II 12V SIP module is
designed for low output ripple voltage and will meet
the maximum output ripple specification with 1 µF
ceramic and 10 µF polymer capacitors at the output of
the module. However, additional output filtering may
be required by the system designer for a number of
reasons. First, there may be a need to further reduce
the output ripple and noise of the module. Second,
the dynamic response characteristics may need to be
customized to a particular load step change.
To reduce the output ripple and improve the dynamic
response to a step load change, additional
capacitance at the output can be used. Low ESR
polymer and ceramic capacitors are recommended to
improve the dynamic response of the module. For
stable operation of the module, limit the capacitance
to less than the maximum output capacitance as
specified in the electrical specification table.
Safety Considerations
For safety agency approval the power module must
be installed in compliance with the spacing and
separation requirements of the end-use safety agency
standards, i.e., UL 60950-1, CSA C22.2 No. 60950-1-
03, and VDE 0850:2001-12 (EN60950-1) Licensed.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power
module has extra-low voltage (ELV) outputs when all
inputs are ELV.
The input to these units is to be provided with a fast-
acting fuse with a maximum rating of 6A in the
positive input lead
