Description
I/O
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

PV
CC
:
The supply voltage terminal for power.
It determines the upper limit of output drive volt-
age. Normally, it is used at the same potential of
SV
CC
.
