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 (after 400 ms) into 1.5x mode.
At power−up, the CAT3616 starts operating in 1x mode
If the input voltage is insufficient or falls to a level where

chip is powered−up or is taken out of shutdown mode (via
EN pin).
In 1.5x mode, the output is approximately equal to 1.5
