1
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.
2 Ground
Power ground.
3
Analog Output
Current compensation. Output of the current error amplifier. Connect a capacitor between
the COMI pin and SGND for frequency compensation.
4
Analog Output
Voltage compensation. Output of the voltage error amplifier. Connect a capacitor between
the COMV pin and SGND for frequency compensation.
5 Analog Input Voltage sense. Output-voltage-sense input for output-voltage regulation.
6 Ground
Signal ground.
7 Supply
Power supply.
8 Driver Output The totem-pole output driver to drive the power MOSFET.
