8 / 12 page DS_NE12S10A_07092013 8 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. DC-DC Converter 1uF Ceramic Tan 10uF Vin+ Load Ltest Cs Cin Output voltage ripple noise measurement point Input reflected current measurement point Cs=270 μF*1, Ltest=2uH, Cin=270μF*1 Figure 23: Input reflected ripple/ capacitor ripple current and output voltage ripple and noise measurement setup for NE10 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. Vin Vout Enable Ground Ground Trim ND 6A/10A Rmargin-down Rs Rmargin-up Figure 22: Circuit configuration for output voltage margining Paralleling NE10 converters do not have built-in current sharing (paralleling) ability. Hence, paralleling of multiple NE10 converter is not recommended. NE6A/10A |
