SYMBOL

DESCRIPTTION

1

EN

Enable pin for the IC. Drive the pin to high to enable the part, and low to disable. Do not float.

4,5

GND

Power Ground

3,6

SW

Inductor connection. Connect an inductor between SW and the regulator output.

2

IN

Power Supply Input Pin.

8

FB

Feedback input. Connect an external resistor divider from the output to FB and GND to set the

7

PG

Power good indicator. When the output voltage exceeds 90% of regulation point, It becomes

open drain low otherwise. Connect this pin to IN by a 1MΩ pull-up resistor.

Note1: Absolute Maximum Ratings are threshold limit values that must not be exceeded even for an instant under

any condition. Moreover, such values for any two items must not be reached simultaneously. Operation above these

absolute maximum ratings may cause degradation or permanent damage to the device. These are stress ratings only

and do not necessarily imply functional operation below these limits.
