Explanation
Equivalent Circuit

Out
O
Output used to directly drive a power MOSFET.
A totem pole structure is adopted in this
output circuit.
The absolute maximum ratings for the output
current are:
Peak:
±
1 A
DC:
±
150 mA

CC
Power supply.
This pin monitors supply voltage and has the
threshold for the start, stop, OVP, and OVP
reset levels.

This pin is used in RM (remote), OVP (over-
voltage protection), and timer latch.
RM:
The IC is in remote operation if this pin is
short-circuited to the ground and the output
of the IC is turned off.
OVP:
When overvoltage signal of the power sup-
ply is detected and high is inputted to the ter-
minal, it turns off the internal circuit. At the
same time, it holds that condition (latch).
Timer latch:
It detects the output voltage fall due to the
overcurrent condition of the power supply
output through the current level inputted to
FB. When the I
FB
decreases under the current
of certain value, the charge current flows in
the capacitor which is connected to this ter-
minal. Then, when the capacitor is charged
up to the threshold voltage of the OVP, the
OVP works so that the IC could keep the op-
eration stop condition.
