For proper operation of the LM3645EVM, the jumpers should be properly configured. The recommended setting, using shorting blocks is:
VIO to VIN
EN to VIO
STR1 and STR2 to PWM1 and PWM2 or external signals
TORCH/TX to PWM0 or external signal
LEDs (J21, J22, J23 and J24) shorted
In this configuration, the device will power up when power is applied.
