Description
Analog Input, Current Sense. Connected to a current-sense resistor for peak-current-mode
control in CV mode. The current-sense signal is also provided for output-current regulation in
CC mode.
Analog Output, Cable Compensation. Connect a resistor between COMR and GND for cable
loss compensation in CV mode.
Analog Output, Current Compensation. Output of the current error amplifier. Connect a
capacitor between COMI pin and GND for frequency compensation.
Analog Output, Voltage Compensation. Output of the voltage error amplifier. Connect a
capacitor between COMV pin and GND for frequency compensation.
Analog Input, Voltage Sense. Output-voltage-sense input for output-voltage regulation.
Supply, Power Supply.
Voltage Reference, Ground.
Driver Output, Power MOSFET Drain. This pin is the high-voltage power MOSFET drain
