Pin Description

Number

Symbol

Function

Drain of NDMOS switch.

GND

Ground (0V).

VSET

Multi-function On/Off and brightness control pin:



Leave floating for normal operation.



Drive to voltage below 0.2V to turn off output current.



Drive with DC voltage (0.3V<VSET<2.5V) to adjust output current

from 12% to 100% of IOUTnom.



Drive with PWM signal to adjust output current. Adjustment range

1% to 100% of IOUTnom for f≤1kHz.

ISENSE

Connect resistor RS from this pin to VIN to define nominal average

output current IOUTnom=0.1/RS.

VIN

Input voltage (6V to 40V). Decouple to ground with 10μF or higher

X7R ceramic capacitor close to device.

GND
