The IC provides several protection features in order to
ensure the PFC system in safe operating range.
Depending on the input line voltage (V

The following sections describe the functionality of
these protection features.
3.4.1
The IC is designed not to support any output power
that corresponds to a voltage lower than -0.75V at the
ISENSE pin. A further increase in the inductor current,
which results in a lower ISENSE voltage, will activate
the Soft Over Current Control (SOC). This is a soft
control as it does not directly switch off the gate drive.
It acts on the nonlinear gain block to result in a reduced
PWM duty cycle.
