Design Considerations
Input Source Impedance
To maintain low-noise and ripple at the input voltage, it is
critical to use low ESR capacitors at the input to the module.
18 shows the input ripple voltage (mVp-p) for various output
models using a 150 µF low ESR polymer capacitor (Pana-
sonic p/n: EEFUE0J151R, Sanyo p/n: 6TPE150M) in parallel
with 47 µF ceramic capacitor (Panasonic p/n: ECJ-
5YB0J476M,
Taiyo Yuden p/n: CEJMK432BJ476MMT). 19 depicts much
lower input voltage ripple when input capacitance is
increased to 450 µF (3 x 150 µF) polymer capacitors in par-
allel with 94 µF (2 x 47 µF) ceramic capacitor.
The input capacitance should be able to handle an AC ripple
current of at least:
