BRL (Brownout, fast AC Reset & Latch enable)
The BRL pin combines the functions of brownout, fast
AC reset and the external latch enable. The brownout
feature is to stop the switching pulse when the input
voltage is dropped to lower than 1V. The Fast AC reset
feature is to recover from latch feature when the
voltage of BRL pin has a rising rate of <1.33V/ms from
0.4V to 1V. The external latch enable function is an
external access to stop the gate switching and force the
IC to enter latch mode. It is triggered by pulling the pin
voltage to less than 0.4V.
FBB (Feedback & Burst entry select)
The FBB pin combines the feedback function and the
burst entry/exit control. The regulation information is
provided by the FBB pin to the internal Protection Unit
and the internal PWM-Comparator to control the duty
cycle. The FBB-signal is the only control signal in case
of light load at the Active Burst Mode. The burst entry
select provides an access to select the entry/exit burst
mode level.

CS (Current Sense)
The Current Sense pin senses the voltage developed
on the shunt 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 operation.
Drain (Drain of integrated CoolMOS^®)
The Drain pin is the connection to the Drain of the
integrated CoolMOS^®.
