Design Considerations
Input Filtering
The Austin MicroLynx
be 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 a typical application, 2x47 µF low-ESR tantalum
capacitors (AVX part #: TPSE476M025R0100, 47µF
25V 100 mΩ ESR tantalum capacitor) will be sufficient
to provide adequate ripple voltage at the input of the
module. To minimize ripple voltage at the input, low
ESR ceramic capacitors are recommended at the input
of the module. Figure 27 shows input ripple voltage
(mVp-p) for various outputs with 2x47 µF tantalum
capacitors and with 2x 22 µF ceramic capacitor (TDK
part #: C4532X5R1C226M) at full load.

ceramic capacitors at the input (80% of Io,max).
