PIN FUNCTIONS

Pin #

Name

Description

1

EN

On/Off Control

2

FB

Feedback pin. An external resistor divider from the output to AGND, tapped to the FB

pin, sets the output voltage.

3

AGND

Analogy ground for internal control circuit

4

OUT

Input sense pin for output voltage

5

PGND

Power ground

6

SW

Switch Output

7

VIN

Supply Voltage. The MP2160 operates from a +2.7V to +6V unregulated input. C1 is

needed to prevent large voltage spikes from appearing at the input.

8

PG

Power Good Indicator. The output of this pin is an open drain with internal pull up

resistor to VIN. PG is pulled up to VIN when the FB voltage is within ±10% of the

regulation level, if FB voltage is out of that regulation range, it is LOW.
