DESCRIPTION

NAME

NO.

COMP

2

O

Output of the transconductance error amplifier. Connect an external capacitor to this pin to

compensate the converter.

CTRL

5

I

Control pin of the boost converter. It is a multi-functional pin which can be used for enable control,

PWM and digital dimming.

FB

1

I

Feedback pin for current. Connect the sense resistor from FB to GND.

GND

3

O

Ground

SW

4

I

This is the switching node of the device. Connect the inductor between the VIN and SW pin. This pin

is also used to sense the output voltage for open LED protection

VIN

6

I

The input supply pin for the device. Connect VIN to a supply voltage between 2.7 V and 18 V.

Thermal Pad

—

Solder the thermal pad to the analog ground plane. If possible, use thermal via to connect to ground

plane for ideal power dissipation.
