FEATURES DESCRIPTIONS (CON.)

Voltage Margining Adjustment

Output voltage margin adjusting can be implemented in the NE modules by connecting a resistor, Rmargin-up, from the Trim pin to the Ground for margining up the output voltage. Also, the output voltage can be adjusted lower by connecting a resistor, Rmargin-down, from the Trim pin to the voltage source Vt. Figure 22 shows the circuit configuration for output voltage margining adjustment.

Vt

Output Capacitance

There is internal output capacitor on the NE series modules. Hence, no external output capacitor is required for stable operation.

Reflected Ripple Current and Output Ripple and Noise Measurement

The measurement set-up outlined in Figure 23 has been used for both input reflected/ terminal ripple current and output voltage ripple and noise measurements on NE series converters.

Paralleling

NE20 converters do not have built-in current sharing (paralleling) ability. Hence, paralleling of multiple NE20 converter is not recommended.
