V
CC
The supply voltage terminal other than the
output. The U.V.L.O. depends on this V
CC
voltage.
(The characteristics of U.V.L.O. are shown in the
right figure.)
<Note on the methods of providing V

The method to give bias from sub-coil
There is only 2 V typical difference between the
start voltage 10 V typical and the stop voltage 8 V
typical. Be careful that the value for C1 shown in the
right figure must be set at a large value, otherwise,
the IC does not easily start.
Giving bias from power supply
In the case such as of fluorescent lamp inverter
circuit, separate power supply is provided so as to
give the bias from the separate power supply.

PV
CC
Drive current supply terminal of output block
The high voltage of the power MOSFET gate
drive pulse is determined by this terminal voltage.
In the case of limiting the power MOSFET
drive current, if the R1 is connected to the PV
CC
terminal and the R2 is connected to the V
OUT
ter-
minal as shown in the right figure, the R1
+
R2
limits the drive current when the power MOSFET
is turned on and the R2 limits the drive current
when it is turned off. In that way, the speed of turn-
on and turn-off can be changed.
