ADP3089ACP -40°C to +85°C CSP-8 3

×3 P7A

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection.

Although the device features proprietary ESD protection circuitry, permanent damage may oc-

cur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD

precautions are recommended to avoid performance degradation or loss of functionality.

PIN FUNCTION DESCRIPTIONS

Pin

Mnemonic

Function

1, 2

IN

Power Supply Input. Both pins

must be connected.

3, 6

GND

Ground. Both pins must be con-

nected.

4

COMP

Feedback Loop Compensation

and Shutdown Input. An open

drain or collector used to pull

the pin to ground will shutdown

the device.

5

FB

Feedback Voltage Sense Input.

This pin senses the voltage via

an external resistor divider.

7

DRV

This pin provides a separate

path for drive current to be con-

nected to ground.

8

SW

Switching Output.
