Design Considerations
Input Filtering
The Austin MicroLynx
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 26 shows the input ripple voltage (mVp-
p) for various outputs with 1x150 µF polymer capacitors
(Panasonic p/n: EEFUE0J151R, Sanyo p/n: 6TPE150M)
in parallel with 1 x 47 µF ceramic capacitor (Panasonic
p/n: ECJ-5YB0J476M, Taiyo- Yuden p/n:
CEJMK432BJ476MMT) at full load. Figure 27 shows the
input ripple with 2x150 µF polymer capacitors in parallel
with 2 x 47 µF ceramic capacitor at full load.
