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.
