PIN FUNCTIONS

Package

Pin #

Name

Description

1

EN

Enable control. EN has an internal auto pull-up current to 5V. Float EN or apply a logic

high voltage to enable the IC. Pull EN to logic low to disable the IC.

2

OUT

Output of USB current limit switch.

3

IN

Supply voltage.

4

GND

Ground.

5

ADJ

Output voltage adjustment. ADJ sinks a current from the upstream DC/DC converter's

FB pin to ground to regulate the DC/DC converter's output voltage. ADJ also supports

line drop compensation.

6

ILIM

Set the current limit level. Place a resistor between ILIM and GND to achieve a high-

accuracy current limit. The current limit threshold varies versus the output voltage to

maintain a fairly constant output power limit.

7

DM

D- data line to USB connector. DM is the input/output used for handshaking with

portable devices.

8

DP

D+ data line to USB connector. DP is the input/output used for handshaking with

portable devices.
