Description

6
V
B
:
The terminal is connected via the transformer's
sub-coil and resistor. The reset of transformer is
detected and the trigger signal to turn on the power
MOSFET is sent.
Since the coil signal of transformer is input as
current, the IC incorporates the circuit which
clamps the upper/lower limit voltage to prevent
malfunction.
I
7
GND:
Grounding terminal
This terminal is used in common for grounding the
control system and the power system.
8
V
OUT
:
The output terminal.
It is capable of driving the gate of power MOSFET
directly.
O

V
CC
:
The supply voltage terminal.
The supply voltage terminal for the power system
and that for the signal system are put together as
one terminal with internal connection in order to
greatly decrease the common impedance.
This double-functioning terminal monitors the
supply voltage, and has start/stop operation thresh-
old.
