Output Capacitance

There is output capacitor on the NE series modules.

Hence, an 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.

FEATURES DESCRIPTIONS (CON.)

Voltage Margining Adjustment

Output voltage margin adjusting can be implemented in

the Trim pin to the Ground for margining up the output

voltage. Also, the output voltage can be adjusted lower

the voltage source Vt. Figure 22 shows the circuit

configuration for output voltage margining adjustment.

Paralleling

NE10 converters do not have built-in current sharing

(paralleling) ability. Hence, paralleling of multiple NE10

converter is not recommended.
