NAME

FUNCTION

1

VIN

2

VIN

Power supply Input of switch. Connect this pin to an external DC supply.

EN

Enable input of switch. Logic high turns on switch. The EN pin cannot be left floating.

3

ENB

Enable input of switch. Logic low turns on switch. The ENB pin cannot be left floating.

4

BIAS

Bias voltage input pin for internal control circuitry.

5

GND

Ground pin of the circuitry. All voltage levels are measured with respect to this pin.

6

SS

Soft start control of switch. A capacitor from this pin to ground sets the VOUT’s rise slew

rate.

7

VOUT

8

VOUT

Switch output.

Exposed Pad

-

Connect this pad to system ground plane for good thermal conductivity.
