Follow these steps for the EVM test: • Set the voltage of the dc power supply to 12 V and set the current limit to 4 A. • Connect four LED strings on the LED board to OUT1 - OUT4 of connector J21. Connect Boost pin of the LED board to the Boost pin of connector J21. (Note: LED current default is 120 mA and maximum boost voltage default is 37 V. LED outputs that are not used must be grounded via corresponding jumpers J16, J19, J20 and J22.) • Connect the positive and negative outputs of the power supply to connectors VBAT and GNDin on the EVM board. • Turn on the power supply. The LEDs will be turned on immediately since the jumpers on the EVM are set for PWM input of 100% duty cycle. For other connector and jumper positions, please refer to Figure 1 and Figure 6.
