Functional Block Diagram

Pin No.

Name

Description and function

DNC

Do not connect

Leave pin floating.

REF

Reference

This pin is connected to VCC via resistor, RREF. Select RREF to source 2.16mA into this pin. Refer to Table

1, in Application Information section.

GATEL

Gate turn off

This pin sinks current, ISINK, from the synchronous MOSFET Gate.

GATEH

Gate turn on

This pin sources current, ISOURCE, to the synchronous MOSFET Gate.

VCC

Power Supply

This is the supply pin. It is recommended to decouple this point to ground closely with a ceramic

capacitor.

GND

Ground

This is the ground reference point. Connect to the synchronous MOSFET Source terminal.

BIAS

Bias

This pin is connected to VCC via resistor, RBIAS. Select RBIAS to source 3mA into this pin. Refer to Table 1,

in Application Information section.

DRAIN

Drain connection

This pin connects directly to the synchronous MOSFET Drain terminal.
