PIN

NAME

Description

1

PGOOD

Assert high once VO reaches 92% of its rating voltage. Open-drain output.

2

EN

Enable Input. (Active High)

3

VIN

Input voltage. Large bulk capacitance should be placed closely to this pin.

A 10µF ceramic capacitor is recommended at this pin.

4

VDD

Input voltage for controlling circuit.

5

NC

Not connected.

6

VOUT

The power output of the device. A pull low resistance exists when deactivate

device by VEN.

7

ADJ

This pin, EC8320A/B when grounded, sets the output voltage by the internal

feedback resistors.If external feedback resistors are used, the output voltage

will be VO = 0.8(R1+R2)/R2 Volts.

8

GND

Reference ground.
