Design Considerations (continued)
Output Filtering
The Austin MicroLynx TM 12V 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
.
