NCP102 Demonstration Board Test Procedure
Required Equipment:
1.
3 DC Power Supplies:
a.
“Vin supply” possessing a minimum voltage rating of 5 VDC
and minimum current rating of 4 ADC; for example, HP
6282A.
b.
“Vcc supply” possessing a minimum voltage rating of 15
VDC and minimum current rating of 1 ADC; for example, ½
Agilent e3649A dual supply.
c. “N_Enable
supply”
possessing
a minimum voltage rating of
5.5 VDC and minimum current rating of 0.1 ADC; for
example, ½ Agilent e3649A dual supply.
2.
3 Auto-ranging Digital Multimeters (DMMs):
each
possessing a minimum voltage rating of 20 VDC and
minimum current rating of 2ADC; for example, Keithley 175.
3.
1 Electronic Load:
possessing a current display and
minimum current capability of 4 ADC; for example, Kikusui
PLZ303W.
Test Procedure:
Establish Setup
1.
Connect the NCP102 Demonstration Board as shown in
Figure 1.
2.
Adjust the N_Enable supply to 4.5VDC while observing the
indicator on the supply.
Note: for measurement accuracy, the DMMs must be connected
to the Demonstration Board terminals and not the DC supply or
load terminals. This is particularly true for DMM 2 and DMM 3.
3.
Connect DMM 1 to Vcc and configure as a voltmeter. Set
DMM 1for auto-range.
4.
Connect DMM 2 to Vin and configure as a voltmeter. Set
DMM 2 for auto-range.
5.
Connect DMM 3 to Vout and configure as a voltmeter. Set
DMM 3 for auto-range.
