Test Procedure for the measurements of the Enable functionality
using Test Setup 2:
1. Connect the test setup as shown on Figure 2,
2. Apply the required input voltage e.g. V
IN
= V
OUT_NOM
+ 0.3V
(1)
3. Set the electronic load for the required load current e.g. I
OUT
= 10mA,
4. Set the square wave generator to generate the following pulse
waveform:
5. Verify with the oscilloscope that the output voltage V
OUT
turns ON/OFF.
6. Turn off the pulse generator.
7. Turn off the electronic load.
8. Turn off the input power supply
9. End of the test

V
OUT_NOM
is the nominal output voltage level of the regulator. NCP702 operating V
IN
must be in the range 2.0V ≤ V
IN
≤ 5.5V
