The NCP5604A chip is capable of driving the four LED
simultaneously, as depicted in Figure 1, but the load can be
arranged to accommodate one or two LED if necessary in
the application (see Figure 8). The four current mirror can
be connected in parallel to drive a single powerful LED,
thus yielding 100 mA current capability in a single LED.

The applications using three LED shall use the
NCP5604B version to make profit of the highest efficiency
(see Figure 9). In this case, LED4 is not connected and pin
5 is internally unconnected.
