Name

Description

1

CS

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

GND

Voltage reference, ground.

3

COMI

Analog output, current compensation. Output of the current error amplifier. Connect a capacitor

between COMI pin and GND for frequency compensation.

4

COMV

Analog output, voltage compensation. Output of the voltage error amplifier. Connect a capacitor

between COMV pin and GND for frequency compensation.

5

VS

Analog input, voltage sense. Output-voltage-sense input for output-voltage regulation.

6

GND

Voltage reference, ground.

7

VDD

Supply, power supply.

8

GATE

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