ADIM
Current Sense. Limits output current, depending on the sensing resistor voltage. The CS pin is
also used to set the LED current regulation.
VCC. Supply pin for stable IC operation; ZCD signal detection used for accurate PFC function.
GROUND. Ground for the IC
RT. Programmable operating frequency using an external resistor; the IC has pre-fixed
frequency when this pin is open or floating.
Analog Dimming. Connect to the internal current source. Use to change the output current
using an external resistor. If ADIM is not used, connect a 0.1µF bypass capacitor between the
ADIM and GND.
High Voltage. Connect to the high-voltage line and supply current to the IC.
DRAIN. The drain pin of internal MOSFET
