Function
Multi-function On/Off and brightness control pin:
? Leave floating for normal operation.(V ADJ = V REF = 1.25V giving nominal
average output current I OUTnom = 0.2V/ RS )

? Drive to voltage below 0.2V to turn off output current
? Drive with DC voltage (0.3V < V ADJ < 2.5V) to adjust output current from 25%
to 200% of I OUTnom
? Connect a capacitor from this pin to ground to set soft-start time.
Soft start time increases approximately 0.2ms/nF
Connect resistor RS from this pin to VIN to define nominal average output current
