PIN DESCRIPTION

Pin

Name

Type

Description

1

PGND

Power

Ground

Power Ground for power, analog blocks. Must be connected to the system ground.

2

SW

Power

Output

Switch Power pin connects power transistors to one end of the inductor.

3

AGND

Analog

Ground

Analog Ground analog and digital blocks. Must be connected to the system ground.

4

FB

Analog

Input

Feedback Voltage from the buck converter output. This is the input to the error amplifier. This pin

is connected to the resistor divider network between the output and AGND.

5

EN

Digital

Input

Enable of the IC. High level at this pin enables the device. Low level at this pin disables the de-

vice.

6

PG

Digital

Output

It is open drain output. Low level at this pin indicates the device is not in power good, while high

impedance at this pin indicates the device is in power good.

7

AVIN

Analog

Input

Analog Supply. This pin is the analog and the digital supply of the device. An optional 1

mF or lar-

ger ceramic capacitor bypasses this input to the ground. This capacitor should be placed as close

as possible to this input.

8

PVIN

Power

Input

Power Supply Input. This pin is the power supply of the device. A 10

mF or larger ceramic capacit-

or must bypass this input to the ground. This capacitor should be placed as close a possible to

this input.

9

PAD

Exposed

Pad

Exposed Pad. Must be soldered to system ground to achieve power dissipation performances.

This pin is internally unconnected
