Description
1 LX
Drain of power switch.
2
GND
Ground (0V).
Multi-function On/Off and brightness control pin:
* Leave floating for normal operation.(VADJ = VREF = 1.2V giving
nominal average output current IOUT_NOM =0.1/RS )
* Drive to voltage below 0.2V to turn off output current.
3 ADJ * Drive with DC voltage (0.3V<VADJ <1.2V) to adjust output current
from 25% to 100% of IOUT_NOM.
* Drive with PWM signal to adjust output current.
* When driving the ADJ pin above 1.2V, the current will be
clamped to 100% brightness automatically.
4
ISENSE
Connect resistor RS from this pin to VIN to define nominal average
output current IOUT_NOM =0.1/RS.
5
VIN
Input voltage (6V ~ 40V). Decouple to ground with 0.1μF X7R
ceramic capacitor as close to device as possible.
