Pin Drain is the connection to the Drain of the internal
CoolMOS® and the HV of the startup cell.

CS
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
integrated CoolMOS®. If CS voltage 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.

BA (extended Blanking & Auto-restart enable)
6
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 to ground. The
external auto-restart enable function is an external
access to stop the gate switching and force the IC to
enter auto-restart mode. It is triggered by pulling down
the BA pin to less than 0.33V.

VCC (Power Supply)
The VCC pin is the positive supply of the IC. The
operating range is between 10.5V and 25V.
GND (Ground)
The GND pin is the ground of the controller.

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.
