Test Procedure www.ti.com
In the GUI 3.3A CONTROL panel, click on the PASS/BLK FET button. In the STATUS panel, verify the
3.3A PASS/BLK FET and VOUT GOOD indicator colors change to GREEN. On the oscilloscope, verify a
waveform was obtained similar to the one shown in Figure 6 . The total ramp time of the Channel 1
waveform, from 0 volts to about 3.2 volts should be 2.6 ± 0.6 mS. The peak amplitude of the current pulse
on Channel 4 (I
PEAK
) should be 195 ± 25 mA. A DVM can be used to verify the voltage at TP8 (with
respect to ground at TP9) is within 10 mV of the 3.3-V input supply voltage at 3V3IN1 (TP2).
