signal, and the voltage on pin #4(Vfb) is lower than 0.8V.
Figure 9. The operation of the FS8S0765RC at the normal
mode and the off mode
During the power saving mode, the Vcc which was regulated
at 22V during the normal mode, fluctuates between 11V and
12V. When the Vcc touches 11V, the FS8S0765RC starts to
switch and when the Vcc reaches 12V, it stops switching.
During the switching periods, the FS8S0765RC has the
switching frequency of 40 KHz and the constant peak MOS-
FET current of 0.6A. Figure 9 shows operating waveforms.
The soft start during the initial start-up is shown in the sec-
tion 1. During this period, there is no external sync signal
and the switching frequency is 20KHz. The section 2 repre-
sents the normal mode operation. The switching frequency is
synchronized with the external sync signal. In the section 3,
the external sync signal is removed, but the load exists and
thus the Vfb is higher than 0.8V. In this period the
FS8S0765RC does the normal switching operation with the
switching frequency of 20KHz. The section 4 and 5 show the
burst mode operation. At the end of the section 3, the load is
also eliminated and at the beginning of the section 4, the Vfb
drops down below 0.8V and the FS8S0765RC stops switch-
ing. During the section 4, the Vcc goes down to 11V. When
the external sync signal appears at the pin 5, the
FS8S0765RC recovers its normal operation.
