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 26 shows the input ripple voltage

(mVp-p) for various output models using 2x100 uF low

ESR tantalum capacitors (KEMET P/N:T491D107M,

100uF/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:

Io = 6A (Cin = 2x100uF tantalum capacitors or

2x22uF ceramic capacitors at the input)

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.
