Design Considerations
Input Filtering
The Austin Lynx
connected to a low-impedance source. A highly
inductive source can affect the stability of the module.
An input capacitance must be placed directly adjacent
to the input pin of the module, to minimize input ripple
voltage and ensure module stability.
Output Filtering
The Austin Lynx
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, CSA C22.2 No. 60950-00, EN60950
(VDE 0850) (IEC60950, 3
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.
