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 28 shows the input ripple voltage
(mVp-p) for various outputs with 1x22µF (TDK:
C3225X5R0J226V) ceramic capacitor at the input of the
module. Figure 29 shows the input ripple with 1x47µF
(TDK: C3225X5R0J476M) ceramic capacitor at full load.
