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. Figure 32 shows the input ripple voltage (mVp-p)
for various output models using 200 μF(2 x100uF) low
ESR
tantalum
capacitor (KEMET p/n: T491D107M016AS,
AVX p/n: TAJD107M106R, or equivalent) in parallel with
47 μF ceramic capacitor (TDK p/n:C5750X7R1C476M or
equivalent). Figure 33 shows much lower input voltage
ripple when input capacitance is increased to 400 μF (4 x
100 μF)
tantalum
capacitors in parallel with 94 μF (2 x 47
μF) ceramic capacitor.
The input capacitance should be able to handle an AC
ripple current of at least:
