Pin description
SOURCE
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
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
dropped below 5 V.
Supply voltage of the device.
A capacitor, connected between this pin and ground, is initially charged by the
internal high-voltage startup generator; when the device is running, the same
generator keeps it charged in case the voltage supplied by the auxiliary winding
is not sufficient. This feature is disabled in case a protection is tripped. A small
bypass capacitor (100 nF typ.) to GND may be useful to get a clean bias voltage
for the signal part of the IC.
