BASIC OPERATION
At power-up, the CAT3604 starts operation in 1x
mode. If it is able to drive the programmed LED
current, it continues in 1x mode. If the battery
voltage drops to a level where the LED current
cannot be met, the driver automatically switches
into 1.5x mode. The 1.5x charge pump will boost
the output voltage accordingly to achieve the nomi-
nal LED current.
Figure 1: CAT3604 Functional Block Diagram
The operating mode is reinitialized each and every
time the chip is powered up or is taken out of
shutdown mode (via EN pin). The use of the control
pins (CTR0, CTR1, CTR2) does not reconfigure the
mode of operation.
