Name

Description

1

VCC

Power supply

This supply pin should be closely decoupled to ground with a ceramic capacitor.

2

DNC

Do not connect

Leave pin floating.

3

BIAS

Bias

Connect this pin to VCC via RBIAS resistor. Select RBIAS to source 0.54mA into this pin.

Refer to Table 1 and 2, in Application Information section.

4

DRAIN

Drain sense

Connect directly to the synchronous MOSFET drain terminal.

5

REF

Reference

Connect this pin to VCC via RREF resistor. Select RREF to source 1.02mA into this pin.

Refer to Table 1 and 2, in Application Information section.

6

DNC

Do not connect

Leave pin floating.

7

GND

Ground

Connect this pin to the synchronous MOSFET source terminal and ground reference point.

8

GATE

Gate drive

This pin sinks and sources the ISINK and ISOURCE current to the synchronous MOSFET

gate.
