PJ3842B
High Performance Current Mode Controller
7-15
2002/01.ver.A

Two

comparators
have
been
incorporated to guarantee that the IC is fully functional before
the output stage is enabled. The positive power supply
terminal (V
CC
) and the reference output (Vref) are each
monitored by separate comparators.Each has built-in
hysteresis to prevent erratic output behavior as their
respective thresholds are crossed. The large hysteresis and
low start-up current of the PJ3842B makes it ideally suited in
off-line converter applications where efficient bootstrap start-
up technique (Figure 33). 36 V zener is connected as a shunt
regulator from V
CC
to ground.Its purpose is to protect the IC
from excessive voltage that can occur during system start-up.
The minimum operating voltage for the PJ3842B is 11V.
