Design Considerations
Input Filtering
The Austin SuperLynx II
connected to a low-impedance AC 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 18 shows the input ripple voltage (mVp-
p) for various outputs with 2x150 µF polymer capacitors
(Panasonic p/n: EEFUE0J151R, Sanyo p/n: 6TPE150M)
in parallel with 2 x 47 µF ceramic capacitor (Panasonic
p/n: ECJ-5YB0J476M, Taiyo- Yuden p/n:
CEJMK432BJ476MMT) at full load. Figure 19 shows the
input ripple with 4x150 µF polymer capacitors in parallel
with 4 x 47 µF ceramic capacitor at full load.
