... REF GND Figure 3. Basic Reference Current Source Load Connection The NCP5602 chip is capable to drive the two 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 4). In this case, the two current mirrors can be connected in parallel to drive a single power full LED, thus yielding 60 mA current capability in a single (eq ...
