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 2x100uF low ESR electrolytic capacitors (Rubycon P/N:50YXG100, 100uF/50V or equivalent) and 1x3.3.0 uF very low ESR ceramic capacitors (TDK P/N: C4532JB1H335M, 3.3uF/50V or equivalent).

The input capacitance should be able to handle an AC ripple current of at least:

Irms	=	Iout	Vout	⎛	−	Vout	⎞
			Vin	⎜ 1		Vin	⎟ Arms
				⎝			⎠

Figure 26: Input ripple voltage for various output models, Io = 3A (Cin =2x100uF electrolytic capacitors 1x3.3uF 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.
