Description
Current Sense. This pin connects a current-sense resistor to sense the MOSFET current for
peak-current-mode control in CV mode and provides for output-current regulation in CC mode.
Cable Compensation. This pin connects a capacitor between COMR and GND for
compensation voltage drop due to output cable loss in CV mode.
Constant Current Loop Compensation. This pin connects a capacitor and a resistor between
COMI and GND for compensation current loop gain.
Constant Voltage Loop Compensation. This pin connects a capacitor and a resistor between
COMV and GND for compensation voltage loop gain.
Voltage Sense. This pin detects the output voltage information and discharge time based on
voltage of auxiliary winding. This pin connects two divider resistors and one capacitor.
Power Supply. The power supply pin for the IC operating current and MOSFET driving current.
This pin is connects to an external V
startup and turn-off are 16V and 5V, respectively.
Ground.
Drain. This pin is the high-voltage power MOSFET drain.
