Pin Function

FB

1

Feedback Voltage. A resistor divider from the output to GND is used to set the

regulation voltage.

VCC

2

Supply Voltage. This pin provides the bias supply for the EM5841. Ensure that a

decoupling capacitor is placed near the IC.

VIN

3

Main Power Conversion Input & Gate driver voltage supply.

PGND

4

Power Ground.

PGND

5

Power Ground.

SW

6,7

Switching node output. Connect to external inductor.

NC

8

Not Connect.

PG

9

Power Good Indicator. Requires external pull-up resistor.

EN

10

Enable. Pulling this pin lower than 0.4V disables the converter.
