Name

Description

1

1

EN

On/off control.

2

2

FB

Feedback. An external resistor divider from the output to AGND (tapped to

FB) sets the output voltage.

3

3

AGND

Analog ground for the internal control circuit.

4

4

OUT

Input sense for output voltage.

5

5

PGND

Power ground.

6

6

SW

Switch output.

7

VIN

Supply voltage. The MP2162A operates from a +2.5V to +6V unregulated

input. C1 is needed to prevent large voltage spikes from appearing at the

input.

PG

Power good indicator. The output of PG is an open drain with an internal

pull-up resistor to VIN. PG is pulled up to VIN when the FB voltage is within

±10% of the regulation level. If the FB voltage is out of that regulation range,

it is low.
