to a low ac-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 3x150 µF polymer capacitors in
parallel with 2 x 47 µF ceramic capacitor at full load.
