Design Considerations

(continued)

Output Filtering

The Austin MicroLynx

TM

II 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

.
