Current Sense. This pin connects a current-sense resistor to detect the MOSFET current for
the output-current regulation in Constant-Current (CC) regulation.
Power Supply. IC operating current and MOSFET driving current are supplied using this pin.
Ground
Voltage Sense. This pin detects the output voltage information and discharge time for
maximum frequency control and constant current regulation. This pin is connected to an
auxiliary winding of the transformer via resistors of the divider.
Constant Current Loop Compensation. This pin is connected to a capacitor between the
COMI and GND pins for compensation current loop gain.
No Connect
Power MOSFET Drain. This pin is the high-voltage power MOSFET drain.
