An appropriate white LED array is required as a load to correctly evaluate the LED7706.
shows a possible assembly of the LED7707 with a WLED test board. This
demonstration board includes 60 white LEDs (150 mA), switches, jumpers and test points
which can be used to easily perform functional testing of the LED7707.
