How to synchronize with external circuit
Type M51996A has no function to synchronize with external
circuit,however,there is some application circuit for
synchronization as shown in Fig.40.

When the bipolar transistor is used instead of MOS-FIT,the
base current of bipolar transistor must be sinked by the
negative base voltage source for the switching-off duration,in
order to make the switching speed of bipolar transistor fast one.
In this case,over current can not be detected by detecting
resistor in series to bipolar transistor,so it is recommended to
use the CT(current transformer).
For the low current rating transistor,type M51996A can drive it
directly as shown in Fig.42.
