Operation notes
(1) 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.
(2)
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 ex-
ceeded, use appropriate physical protective measures
(fuses etc.).
(3) Set the dead-time input voltage to 0.58V or more.
(4) This IC does not use an internal circuit to generate
the output on peak current, so we recommend that you
connect capacitors to each end of R
BIAS
to externally gen-
erate the on peak current (after taking power dissipation
and efficiency into consideration). In this case, there is a
possibility that the output waveform may become unsta-
ble due to the current impedance, so we recommend that
you connect resistors (of about 100
Ω
to 500
Ω
) in series
with the off peak capacitors.
