LIM/OPP
Ipeak set / Over
power limitation
The current drown from the pin decreases Ipeak of the
primary winding. If resistive divider from the auxiliary
winding is connected to this pin it sets the OPP compen-
sation level (it diminishes the peak current.)

This is the inverting input of the trans conductance error
amplifier. It is normally connected to the switching power
supply output through a resistor divider.

Compensation
The error amplifier output is available on this pin. The
network connected between this pin and ground adjusts
the regulation loop bandwidth. Also, by connecting an
opto−coupler to this pin, the peak current set point is
adjusted accordingly to the output power demand.
