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 28 shows the input ripple voltage
(mVp-p) for various output models using 2x47 uF low
ESR tantalum capacitors (SANYO P/N:16TPB470M,
47uF/16V or equivalent) or 2x22 uF very low ESR
ceramic capacitors (TDK P/N:C3225X7S1C226MT,
22uF/16V or equivalent).
The input capacitance should be able to handle an AC
ripple current of at least:
Figure 28: Input ripple voltage for various output models,
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the module. An
input capacitance must be placed close to the modules
input pins to filter ripple current and ensure module
stability in the presence of inductive traces that supply
the input voltage to the module.
