BL (Blanking and Latch)
The BL pin combines the functions of extendable
blanking time for entering the Auto Restart Mode and
the external latch enable. The extendable blanking time
function is to extend the built-in 20ms blanking time by
adding an external capacitor at BL to ground. The
external latch enable function is an external access to
latch off the IC. It is triggered by pulling down the BL pin
to less than 0.1V.
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 controls in case of light load the Active Burst
Mode of the controller.

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