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 in the presence of
inductive traces that supply input voltage to the
module.
In a typical application, a 22 µF low-ESR ceramic
capacitors will be sufficient to provide adequate ripple
voltage at the input of the module. To further
minimize ripple voltage at the input, additional
ceramic capacitors are recommended at the input of
the module. Figure 26 shows input ripple voltage
(mVp-p) for various outputs with 10µF and with a
22µF ceramic capacitor at full load.
