An LED load board LP886X-LEDLOAD-EVM is included in the EVM kit. The LED board is intended to be used as the load for LED driver and can be configured for up to 6 strings and up to 20 LEDs in the string (Number of LEDs in use is defined by jumpers). The initial setting on the board is 8 LEDs in series per string. Cree XLamp ML-C LEDs with maximum current of 350 mA (for parallel use) and maximum forward voltage of 3.4 V at 100 mA (3.2-V typical) are used on the board.
