Design Considerations (continued)
Output Filtering
The Austin SuperLynx TM II 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.
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 20A in the positive
input lead
