Type

Power Input

IC power supply.

VSENSE

Analog Input Auxiliary voltage sense. Used for primary-side regulation.

Digital communication link signal. Used for secondary-side to primary- side

communication for all rapid charge information, which includes output voltage

requests, output current limits, output voltage undershoot, and over-voltage

protection.

DLNK

Analog Output

Primary-side current sense. Used for cycle-by-cycle peak-current control and

Analog Input limit in primary-side CV/CC regulation. During conﬁguration stage, used to

conﬁgure the CDC compensation level.

CS/CDC

GND

Ground

Output

Ground.

GATE

Gate drive for external MOSFET switch.
