Description
Drain of power switch
Ground (0V)
Multi-function On/Off and brightness control pin:
* Leave floating for normal operation.(V
I
* Drive to voltage below 0.2V to turn off output current
* Drive with DC voltage (0.3V<V
* 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.
Connect resistor R
