Pin Functionality
BA (extended Blanking & Auto-restart)
The BA pin combines the functions of extendable
blanking time for over load protection and the external
auto-restart enable. The extendable blanking time
function is to extend the built-in 20 ms blanking time by
adding an external capacitor at BA pin to ground. The
external auto-restart enable function is an external
access to stop the gate switching and force the IC enter
auto-restart mode. It is triggered by pulling down the
BA pin to less than 0.33V.

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. The FB-
Signal is the only control signal in case of light load at
the Active Burst Mode.

CS (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
integrated CoolMOS® If voltage in CS pin reaches the
internal threshold of the Current Limit Comparator, the
Driver output is immediately switched off. Furthermore
the current information is provided for the PWM-
Comparator to realize the Current Mode.
