Operation notes
(1) Set the dead-time input voltage to 0.73V or more.
(2) Use short and wide wiring tracks for the power sup-
ply and ground to keep the mutual impedance as small
as possible, and use inductors and capacitors to keep
ripple to a minimum.
(3)
Set R
DUTY
so that the drive stage and the MOS drive
stage for the synchronous rectifier channel are not on at
the same time.
(4)
If you are not using the external trigger input (pin 13)
for overload output cutoff, pull it up to V
CC
(pin 28).
(5) Great care has been paid to the quality of this com-
ponent. However, if the absolute maximum ratings for
temperature and applied voltage are exceeded, the IC
may be destroyed. Since it is not possible to predict
whether it will be in short mode or open mode if the IC is
destroyed, if there is a chance that the maximum ratings
of the IC will be exceeded, use appropriate physical pro-
tective measures (fuses etc.).
