FL7701 PIN CONFIGURATION
CS HV OUT NV VCC GND RT ADIM
Figure 3. Pin Configuration PIN DEFINITIONS Pin No. Name Description
1 CS Current Sense. Limits output current depending on the sensing resistor voltage. The CS pin is also used to set the LED current regulation 2 OUT OUT. Connects to the MOSFET gate. 3 VCC VCC. Supply pin for stable IC operation ZCD signal detection used for accurate PFC function. 4 RT RT. Programmable operating frequency using external resistor and the IC has pre−fixed frequency when this pin is open or floating. 5 ADIM Analog Dimming. Connect to the internal current source and can change the output current using an external resistor. If ADIM is not used, it is recommended to connect a 0.1 mF bypass capacitor between the ADIM and GND. 6 GND GROUND. Ground for the IC. 7 NC No Connection 8 HV High Voltage. Connect to the high voltage line and supply current to the IC
