Description
Current Sense. This pin connects a current-sense resistor to detect the MOSFET current for
peak-current-mode control in CV mode and provides the output-current regulation in CC mode.
Power Supply. IC operating current and MOSFET driving current are supplied using this pin.
This pin is connected to an external V
startup and turn-off are 16V and 5V, respectively. The operating current is lower than 5mA.
Ground
Cable Compensation. This pin connects a 1µF capacitor between the COMR and GND pins
for compensation voltage drop due to output cable loss in CV mode.
Voltage Sense. This pin detects the output voltage information and discharge time based on
voltage of auxiliary winding.
High Voltage. This pin connects to a bulk capacitor for high-voltage startup.
Driver Output. Power MOSFET drain. This pin is the high-voltage power MOSFET drain.
