Function

CS

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.

PGND

2

Ground

Power ground.

COMI

3

Analog Output

Current compensation. Output of the current error amplifier. Connect a capacitor between

the COMI pin and SGND for frequency compensation.

COMV

4

Analog Output

Voltage compensation. Output of the voltage error amplifier. Connect a capacitor between

the COMV pin and SGND for frequency compensation.

VS

5

Analog Input

Voltage sense. Output-voltage-sense input for output-voltage regulation.

SGND

6

Ground

Signal ground.

VDD

Supply

Power supply.

GATE

8

Driver Output

The totem-pole output driver to drive the power MOSFET.
