Design Considerations
Input Filtering
The 12V Pico TLynx
TM 6A module should be
connected to a low ac-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.
To minimize input voltage ripple, ceramic
capacitors are recommended at the input of the
module. Figure 40 shows the input ripple voltage
for various output voltages at 6A of load current
with 1x10 F or 1x22 F ceramic capacitors and
an input of 12V.

Output Filtering
The 12V Pico TLynx
TM 6A modules are designed for
low output ripple voltage and will meet the maximum
output ripple specification with 0.1 F ceramic and 10
F 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
polymer and ceramic capacitors are recommended to
improve the dynamic response of the module. Figure
41 provides output ripple information for different
external capacitance values at various Vo and for a
load current of 6A. For stable operation of the
module, limit the capacitance to less than the
