OPERATION
At power-up, the CAT3603 starts operating in 1x mode
where the output will be approximately equal to the input
supply voltage (minus any internal voltage losses). If the
output voltage is sufficient to regulate all LED currents,
the device remains in 1x operating mode.
If the input voltage falls to a level where the regulated
currents cannot be maintained, the device automa–
tically switches into 1.5x mode.
In 1.5x mode, the output is approximately equal to 1.5
times the input supply voltage (minus any internal
voltage losses), and high enough to achieve the
nominal LED current.
The above sequence is reinitialized every time the
chip is powered-up or is taken out of shutdown mode
(via EN pin).
