This pin combines the function of Soft Start in case of
Start Up and Auto Restart Mode and the controlling of
the Auto Restart Mode in case of an error detection.

FB (Feedback)
The information about the regulation is provided by the
FB Pin to the internal Protection Unit and to the internal
PWM-Comparator to control the duty cycle.

Isense (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
integrated CoolMOS™. When Isense reaches the
internal threshold of the Current Limit Comparator, the
Driver output is disabled. By this means the Over
Current Detection is realized.

SoftS (Soft Start & Auto Restart Control)
The SoftS pin combines the functions of Soft Start
during Start Up and error detection for Auto Restart
Mode. These functions are implemented and can be
adjusted by means of an external capacitor at SoftS to
ground. This capacitor also provides an adjustable
blanking window for high load jumps, before the IC
enters into Auto Restart Mode.
