I am testing the UCD3138PSFBEVM-027 and have few queries regarding it:
1. The delta between no load and full load waveforms given in SLUUAK4 (Figure 9 and Figure 10) is very less.
Also we are unable to see proper phase shift on the DSO with the change of load, as can be seen in the operational waveform of PSFB (Figure 24).
2. The behavior of tested gate signals of SR mos (red and green) seems different at no load or very light load as compared to the waveforms given in SLUUAK4 (Figure 9)
