N. Name Function
1 SOURCE Source connection of the internal power section.
2CS
Current sense input.
Connect this pin to the SOURCE pin (through an R1 resistor) to sense the
current flowing in the MOSFET through an R
SENSE
resistor connected to GND.
The CS pin is also connected through dedicated ROS, RPF resistors to the input
and auxiliary voltage, in order to modulate the input current flowing in the
MOSFET according to the input voltage and therefore achieving a high power
factor. See dedicated section for more details.
The resulting voltage is compared with the voltage on the ILED pin to determine
MOSFET turn-off. The pin is equipped with 250 ns blanking time after the gate-
drive output goes high for improved noise immunity. If a second comparison level
located at 1 V is exceeded, the IC is stopped and restarted after V
CC
has
dropped below 5 V.
