Design Considerations (continued)
Safety Considerations
Output Filtering
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.
The Austin MiniLynxTM SMT module is designed for
low output ripple voltage and will meet the maximum
output ripple specification with 1 µF ceramic and 10
µF tantalum 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.
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.
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.
