Output Filtering
The TLynx
voltage and will meet the maximum output ripple
specification with 0.1 µF ceramic and 10 µF ceramic
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 ceramic and
polymer capacitors are recommended to improve the
dynamic response of the module. Figure 36 provides
output ripple information for different external
capacitance values at various Vo and for load currents
of 20A while maintaining an input voltage of 5V. Fig 37
shows the performance with a 3.3V input. For stable
operation of the module, limit the capacitance to less
than the maximum output capacitance as specified in
the electrical specification table. Optimal performance of
the module can be achieved by using the Tunable
Loop

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
0850:2004-09 (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
