SimpleSync
TM
and Shoot-Through
Steady state operation under constant load gives
an excellent indication of the ZXRD series
performance and also demonstrates how well
SimpleSync
works. The SimpleSync
TM
technique drives the synchronous MOSFET gate
using the overwinding on the main inductor. It
also uses the high speed suppression characteristics
of the ferrite bead to prevent shoot through
currents. Fig.3 shows the gate waveforms for the
main and synchronous MOSFET devices (Zetex
ZXM64N02X).

Output Voltage Ripple
Output voltage ripple is shown in Fig.4 and Fig. 5
for load currents of 0.5A and 4A respectively.
Output voltage ripple will be dependant, to a very
large extent, on the output capacitor ESR. (see
Applications Section for ripple calculation).
