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 27 shows 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 28 shows
the input ripple with 2x150 µF polymer capacitors in
parallel with 2 x 47 µF ceramic capacitor at full load.
