Basic Operation
where the output will be approximately equal to the input
supply voltage (less any internal voltage losses). If the
output voltage is sufficient to regulate all LED currents, the
device remains in 1x operating mode.
the regulated currents cannot be maintained, the device
automatically switches into 1.33x mode (after a fixed delay
time of about 400 ms). In 1.33x mode, the output voltage is
approximately equal to 1.33 times the input supply voltage
(less any internal voltage losses).

device will automatically switch to the 1.5x boost mode
(after a fixed delay time of about 400 ms). In 1.5x mode, the
output is approximately equal to 1.5 times the input supply
voltage (less any internal voltage losses).
drive the LEDs, it will automatically switch again into 2x
mode where the output is approximately equal to 2 times the
input supply voltage (less any internal voltage losses).
drive all LED currents in 1x mode, it will change
automatically back to 1x mode. This only applies for
changing back to the 1x mode
