Design Considerations
Input Filtering
The Austin MiniLynx
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.
To minimize input voltage ripple, low-ESR polymer
and ceramic capacitors are recommended at the input
of the module. Figure 28 shows the input ripple
voltage (mVp-p) for various outputs with 1x22µF
(TDK: C3225X5R0J226V) ceramic capacitor at the
input of the module. Figure 29 shows the input ripple
with 1x47µF (TDK: C3225X5R0J476M) ceramic
capacitor at full load.
